Form in music is similar to making a sandwich, with different sections labeled like slices of bread and meat. The "A" sections bookend the "B" section in the center, mirroring how slices of bread surround a slice of ham. Understanding a song's form requires studying its labeled parts, just as knowing what goes in a sandwich relies on identifying the bread and filling. The example children's song has an AABB structure, repeating sections labeled A then B.

3. In music, creating a song is just like making a
sandwich. A slice of bread comes first, then a slice
of ham, and then another sliced of bread is added.
The slices of bread represents the same parts of a
song. The slice of ham is a different part of the
song.

4. Music has form. Form is the structure of a
song. When musicians write a song, they
think of its form.
To know the form of a song, you have to
study its parts. Parts of music are labeled
using the letters of the alphabet.
