Title: Forms of Music.
Post by: japjisingh on October 08, 2011, 03:55:51 PM

I know it's quite a silly but I've been getting silly answers everywhere. :P

So the question is-suppose we have a piece with ABA form with the last A having minute changes in that section. And someone asks me total NUMBER of main sections in that particular piece so would it be 2 main sections or 3 main sections?

Technically it's three sections since the A section is repeating at the end.

Just like a Rondo (ABACA). You wouldn't say a Rondo has 3 sections, because it technically has 5.

Thanx a lot! That helped! Btw I read some form style which had ABA' or something like that. So what's A'?

I think I ran into that yesterday.  My theory book introduced binary and ternary music.  In the binary there was "rounded binary" where A repeated, but it ended in a cadence of a different key, while in ternary the A also repeated, but it stayed exactly the same.  So I was told that the first one should actually be called ABA' because the second A was not exactly the same as the first A.  So I'm thinking that in ABA', the A' means it's almost the same but not exactly.

Hmmm... And any idea how would we speak it? ABA'?

ABA' is spoken, " A, B, A prime."  The ' is read "prime."
