Q：This is amazing...How are musicians trained to know how fast a pace is, like Allegro or allegretto?
A：Usually, the tempo is put on the top left of the piece. As they practice, the tempo comes naturally to them. Also, they look to the conductor in the front of the stage to set their tempo. He is the leader of the orchestra.
Q：Why people will use Double-Dotted Note and Triple-Dotted Note for creating Music? Instead of just writing another note and put a slurred sign on the notes?
A1：I believe what your asking is tying notes together. As a piano player, the fewer notes I need to read, the better. If I read a dotted half note followed by a 1/4 rest, that entire measure is written with 2 symbols, versus a half note, a 1/4 note, plus a tie, plus the 1/4 rest (4 symbols).
A2：Either one is correct. Same as we could say "I have" instead of "I've". They mean the same thing, it just gets the job done quicker.
Q：If there is something such as a 32nd note, is there a 64th note?
A：Yes, there are 64th notes. There are also 128th notes. In theory, you could also have 256th and 512th notes, although notes with such small values are very rarely seen in actual compositions.
Q：If you want the note to still last longer, can you put 2 dots? If not, why do some of the notes have 2 dot beside them?
A：Yes. you can put two dots and is often called "double dotted."The dots don't simply mean 'longer' they mean 'half-again-as-long.' E.g. just as one plays a dotted half-note the same length as three quarter notes, one plays a double dotted half-note the same length as seven eighth notes.
Q: Do singers/music bands use this stuff for making music for their songs ?
A: I've known bands that don't use this stuff. They all play by ear, work out their parts on the fly, and memorize. But if you are going to share your music with folks you are not recording with, or if you have a lot of parts in your group, or the music is very long and/or complicated, you will probably use this stuff. Self-taught musicians may not know this stuff, but anyone with formal music training learns it.
答：首先，没有某个单独的符号能代表3拍，或1.5拍等等。如果本该延长某个音的时值，却在演奏时没有延长，这会影响到这段合奏或独奏的效果的。附点就是一种延长音符时值的方法，有了附点，你就不用去读太多的延音连接线了。附点并不是半个音符时值，而是增加它所附的音符时值的一半。例如2+ (2/2) =3 拍。如果是半拍，四分之一拍等等，它们有另外的标记符号。希望这对你有帮助。
Q：I am also a beginner at this. I've played guitar for about 2 years now, and I never really learned how to read music. Therefore, I am a little confused. In regards to the dot idea. Why can not someone simply put in the correct note instead having to halve the note with a dot?
A：Well first off their is no ONE symbol to show 3 beats or 1 and a half ect. , which can effect a concert or solo by not extending the note value as it was supposed to be. The dot is a way to extend a note value in a way, so that you don't have to read ties as much, the dot does NOT half a note value, but adds half of its own value. Example 2+ (2/2) =3 beats. To do half beats, quarter beats, etc their are other symbols. Hope that helps.
Q：this may be kind of stupid but im a beginner. why are some of the notes upside down?
A：It's a combination of both ease of reading and clarification when there are multiple people/instruments involved in the piece. It has absolutely no effect on the notes.
This is mentioned in the Lesson 1 video if you want to hear more about it.
Q：Does Music involve Math in it?
A：Yes, you could say it does, for example the time signatures and rhythm can be seen as fractions. In theory or harmony there is a lot of logic and rules as well, however you wouldn't necessarily need to make calculations in music.
答：大约公元前1000年左右，一个叫圭多·德·阿雷佐的帅小伙，在音乐理论上取得了很多的进展。首先他是第一个通过增加拍子记号，让标准的五线谱变得更容易读记。然后他发明了视唱练耳。这是声乐的音阶：do, re, mi, fa, so, la ,ti, do
Q：who invented the notes for music?
A：In around 1000 CE a guy named Guido D'Arezzo made many improvements in music theory. First he improved standard notation to be easier to use by adding time signatures. Then he made solfege. This is the vocal note scale: do, re, mi, fa, so, la ,ti, do.
Q：ok, i'm a beginner at music and i really want to play the piano but i don't know how because i don't know how to read the notes. for example, what note goes to what key? can someone please tell me which video teaches me how to read the notes? thank you and please answer! someone...... :(
A：Another tip I have is to google a piano with the note names- it will show you which notes are where (you can find this in relation to the groups of two or three black keys). If you can find a real piano to use, you can grab post-it's and label your keys to start. That can help you keep track of which notes are which. Writing in notes on the page under the staff can help and this is an easier way to begin and get the feel for which notes are which. Another tip for piano is to work slowly, separate each hand and then put them together at as slow of a tempo as needed to be able to use both hands simultaneously and then slowly speed up. Use a metronome if you need (easily found online or as apps). There are also youtube videos that show the keys as well as the notes as you go.
答：是的，你可以这样说，相对于这个乐曲的节奏来说，它们演奏的很快。那么想想看，一个四拍的小节。每个小节，有四拍。四分音符可以数成，1，2，3，4。一个音符一拍。八分音符可以数：1嗒，2嗒，3嗒，4嗒（one - and, two - and, three - and, four - and.）。就是两个音符一拍。十六分音符数成one - e - and - a, two - e - and - a, three - e - and - a, four - e - and – a。四个音符一拍。它们都是均匀的出现在小节里的，就像前面我所说的，“快，是相对于节奏而言的”。希望对你有帮助。
Q：I've been in my school band for two years but I still don't understand sixteenth notes,3:31, r they played fast or what?
A：Yes, you could say they are fast, relative to the tempo of the music being played.
So consider a four beat measure. In every bar, there are four beats.
Quarter notes count one, two, three, four. One note played for each beat.
Eighth notes count one - and, two - and, three - and, four - and. So two notes for each beat.
Sixteenth notes count one - e - and - a, two - e - and - a, three - e - and - a, four - e - and - a. That's four notes per beat. They're all evenly measured, so as I said above, 'fast' depends on the tempo. Hope this helps.
Q：When will we get to the point when what sound does the notes make?And I'm just starting music so don't judge me please. But what sounds are we working with? Is it high or low?
A：So far the Khan academy music section does not offer lessons on how to read the staff, hopefully it will in the future though.
What this lesson is teaching is notes and rests. They can be any sound you want them to be. The note type (quarter note, half note, etc.) only tells you how long the note lasts. You can tell how high or low the sound is (also called pitch) by seeing where the note is on the staff. In these videos, they just do not show the notes on the staff so that they don't confuse people who haven't yet learned how to read music.
Hope you have fun learning music!
Q：Can the dotted rests be tied together in the same fashion as the dotted notes?
A：Not really. There isn't really point. If there was a whole note and then there was 2 half notes, that is different. You have to rearticulate. However, with rests, there is no rearticulating. You just rest. There's a lot to worry about when you play a note but when there's a rest, it's just a rest. You simply don't play. This makes it unnecessary to tie rests together.
答：16分音符的拍子，也就是时值取决于拍子记号。不过绝大多数都是四四拍的。在四四拍中，16分音符相当于一拍的四分之一。如果去数一个16分音符的完整小节，就是1-e-and-a, 2-e-and-a, 3-e-and-a, 4-e-and-a，一拍被分成四下，但不要和四分音符搞混淆了。
Q：ok, so at 3:19 he mentioned 16th notes. Could someone explain those to me? I'm clueless because I play guitar and Ukulele and I don't have to read music for them. I want to learn to play violin. but I can't read music very well, yet. So, uber stupid, but how many beats are in a 16th note? 16?
A：The beats/value of a sixteenth note varies depending on the time signature, but the most common time is 4/4. A sixteenth note in 4/4 time receives a 1/4 of ONE beat. When counting a full measure of sixteenth notes, it would be 1-e-and-a, 2-e-and-a, 3-e-and-a, 4-e-and-a. ONE beat is divided into quarters, but do not confuse this with quarter notes!
As I'm sure the video explained, a sixteenth note has 2 flags or a double-bar across the top. Remember: it's a BEAT divided in four, not a MEASURE divided in four.
Also, good luck learning the violin!
Q：how many beats does a 2048 note worth
A：Honestly such a thing never really occurs in music. If a composer needs a note that is quicker than a 32 or 64 note, they just add a grace note, which is a lightly played, quick note before another note.
问：在1分05秒中，提到附点会增加音符时值的一半。那么一个二分音符就是二分音符加二分音符的一半，就是1/2 + 1/4。这就是一个3/4音符，对吗？另外，我说的是在四四拍中。我对这个附点有些不太理解，请帮帮我。
Q：At 1:05, it is said that the dot increases the note value by half. so a half note would be half+ half of half, which is 1/2 + 1/4.This makes a 3/4 note, right? By the way, all of this is in 4/4 time signature. I'm confused with the dot, please help!
A：Basically yeah!! You can kinda think of the dot stealing other notes places :)
答：有，不过主要是在古典音乐中使用。列奥波尔得·莫扎特（举世闻名的沃尔夫冈·莫扎特的父亲），是第一个在他的小提琴教科书（1769年第二版）中使用双附点音符。他的儿子沃尔夫冈·莫扎特，我觉得是第一个使用三附点音符的，在他1782年创作的D大调交响曲中。如果你点查看(加载需要时间http://www.cslsj.gov.cn/images/092016/sfna1xmrcll there Double-Dotted Note and Triple-Dotted Note? If yes, which music piece(s) has use these?
A：Yes, but they are mainly used in older music. Leopold Mozart (the more commonly known Wolfgang Mozart's father) was the first to use the double dot in his book Violin School, second edition, in 1769. His son Wolfgang Mozart was, I believe the first to use the triple dot, in his Symphony in D in 1782. If you click the view button for the overture to this piece, you will see that Mendelssohn uses the triple dot in the second bar in the fifth instrument. (Warning the page takes a moment to load.) http://www.cslsj.gov.cn/images/092016/l02jxc5fnkh learnt different names for the notes. Like a quarter note is known as a 'crotchet'. So have I done a mistake?
A：It's never a mistake to learn something if it truthful and correct. It is actually quite helpful to know the other names (crotchet and such). For instance I never knew the European names until recently, but I got a great theory book that is from the unisa theory program. Since it is from south Africa, it uses all those names. If you ever use a course book from another country, chances are it will use those names. It's kinda like knowing another language. You won't need to know it for everyday life most times, but once in a while it is very useful.
Q：This probably pertains more to the last video than this one, but I just thought of it now. Can the time signature be any combination of numbers at all? Is there a beginning and end to how small or large it can be?
A：The top number can basically be what ever number but 2-12 is most common. The bottom number has to refer to a note as the beat so it can't be a 5 or 7 or a number like that. Because the time signature designates the feel of the piece it's not likely to be a large number. Even 12/8 is like 4/4 just with triplets.
Q：How many beats would be in 2/4? Whats the diffrence?
A：In 2/4 time, there are two beats and the quarter note gets one beat.
Q：At 1:29 it explains that using the dot or the tie are interchangeable. But why are there two options? When would you use the dot and when would you use the tie?
A：The dot is more commonly used on half notes, quarter notes, and eighth notes. It's neater to use the dot but sometimes composers decide not to. When the note extends over the bar line you have to use the tie but other that it doesn't really mater.
Q：At 0:53, I noticed that some notes have the dots directly under them. What does that mean?
A：Dots under or above notes are called staccato which is a form of articulating notes to produce a short, and sharp sound. At 0:53, when the string have staccato eighth notes, they usually use a spiccato stoke, which requires the bow o bounce at the frog and is the slowest of all off string strokes for string instruments.
答：帮助音乐家们把握节奏的一种方法，是用脚拍动，在大脑中听它的拍子。更为复杂的节奏，通常包含八分音符/附点八分音符/附点四分音符，他们会在大脑中细分，或者是用脚拍动细分。细分就是，我们不按四四拍中的1 2 3 4去数每拍，而是数每拍和它们之间的拍子（四四拍这样数：1嗒 2嗒 3嗒 4嗒，这个嗒就是之间的拍子）。这个是数八分音符（在四四拍中，一个小节中有八个八分音符），而不是四分音符（在四四拍中，一个小节有四个四分音符）。
Q：How do musicians count notes in harder pieces?
A：One thing that helps musicians to count rhythms is to tap their foot to the beat of hear it in their heads. With complicated rhythms, usually with eighth/dotted eighth/dotted quarter notes they will subdivide in their head or with their foot. Subdividing is when instead of counting every beat (one, two, three, four in 4/4), you count each beat and the in-between beat (one and two and three and four and in 4/4, the ands are in-between beats ). This is counting every eighth note (eight of them in a 4/4 measure), instead of every quarter note (four of them in a 4/4 measure).
Q：Can you tie rests rather than putting a dot after them like you can with notes?
A：Rests don't ever get tied, they are just written one after another. They can be dotted, just like their note counterparts, but if you wanted 2.5 beats of rest in 4/4 time, you could either write a double-dotted half rest (less common) OR a half rest followed by an eighth rest. Because they are silence, as opposed to of sound, they automatically "tie" together when performed.
Q：if you play a quarter note like 6 times and put a dot after it does that mean that instead of 6 notes there is 7 notes?
A：A dot does not change how many notes you play, it just changes the length of the note. For example, if you played a dotted half note (a half note is two beats) it would last three beats instead of one. So if you played six half notes and the last one is dotted, then it would have thirteen beats instead of twelve. I home that makes sense :)
Q：why do the people playing not have separate music papers than the rest of the others like the clarinets have the clarinet music and trombones have trombone music and so on ?
A：What you are seeing in the video is the conductor's score. It has all the instruments on top of each other. It's the master list, so to speak.
Each individual musician has their own sheet which only has their part. Also, there can be different parts for the same instrument. For example, if you have a section of 9 trumpets, 3 can be playing the 1st part, which is the most complex or challenging. A few more could be playing the second part, which is usually similar. And so on...
Q：Is there a way you can combine more than one different type of note to make a whole note like A half and 2 4ths ?
A：Yes you can. ( if the measure is 4/4 usually)... chech it out... In the video at 1:25...Hope that helps.
Q：at 3:40 in the second bar why are the quarter notes upside down and right side up and have bars connected to the stem of the note?
A：Usually the stem goes up or down depending on where it is on the stave because it fits better. Any notes above the middle line have their stems pointing down and and below the middle line have them pointing up. However, sometimes it's necessary to write more than one part in one stave. This can happen in piano pieces where one hand plays two lines to get a three-part texture, or in orchestras there are sometimes more than one line in each instrument - on stringed instruments this can sometimes be played by double stopping (where everyone in the section plays all the notes which are written) or if this is not possible, or in woodwind/brass instruments where it is only possible to play one note at a time, they section would divide so on each desk, one person plays one line and their desk partner would play the other line. In cases like these, it makes more sense to have the top line with stems pointing up at the lower line with stems pointing down because it's much clearer to read so everyone immediately knows which part is theirs. This is also used in short score for SATB choirs. The bars are showing the rhythm - when we draw single eighth notes, they have a flick on the end of the stem. 16th notes have two of these, 32nd notes have three, and so on. When we beam these notes, we still need to know what the note values are in order to play the right rhythms, so the first beam connecting the notes shows us they are quarter notes, and any beams after that are replacing the extra flicks on the stems.
Q：I am curious how do the musicians start from the bottom and rise from the top so quickly and had obstacles their whole way through?
A：The answer is a one-worder. Perseverance. They persevered against the odds and managed to make it to the top, probably by practicing in almost all of their free time.
Q：I still don't get what the dot is for?
A：It adds half its value. Example: Dotted half note. the two beats plus one. 3 beats
dotted quarter note. one beat plus half a beat is 1 and(1 +).
and so on and so forth. Hope it helps :)
