Bach Musette in D Major

[musicbeginner]

Hello,

Yes, I am back with another question, but a very short one. I am having trouble finding the form of this piece.

I am thinking it is Binary form?

0-0.13 is A
0.13-0.21 is A
0.21-0.34 is B
0.34-42 is A
0.42-0.55 is B
0.55-end is A

I'm sorry to ask another question. It's just that I am taking an intro to music class and I am very confused. I really like my teacher, but I'm just horrible with listening to music and trying to figure out certain things. Plus, I don't want to bug my teacher constantly. Music theory is like math to me...I just don't understand it. I'm a visual learner, so listening to anything can be hard for me to concentrate on. 



Thanks for any clarifications anyone can give!

It's ternary and missing its da capo al fine.  Obviously by a kid - probably one of his sons.

Can you explain how it is ternary form? The only thing I know about Ternary is that it is in a lot of pop songs, ABA...but I don't see how that form fits this song!

Once you get to the end you go back and repeat the the first section to finish.  That's why the first section ends in DM.  If it were binary it would end in AM.  It's just missing the Da Capo instructions.

So, it is just a standard ABA form?

So, it is just a standard ABA form?

If only life were that simple.  If you look at the Musette in Bach's English Suite no 3 (Gavotte II) you see it should be followed by a replay of Gavotte I.  That's ABA in the sense of Gavotte I - Gavotte II - Gavotte I which is probably a standard practice.  Whoever asked you to look at Musette in D was giving you something over you head (and probably over theirs).

Since you have correctly identified the sections, identifying ternary vs. binary should be easy since you know the ternary piece ends with the A section.  Whereas binary is basically always AABB.  Unfornately when you get into examples of "rounded binary" the distinction is less clear.

There was a period in time when you might expect a pop song to go: verse, verse, bridge, verse (AABA).  Looks like ternary form.  Only thing is, these examples of pop songs are typically 50+ years old.  Since the chorus became a big part of pop music, I don't think it neatly fits the idea of ternary form very often.
