In jazz, the augmented second comes up quite a bit. Mainly when dealing with the Jazz minor (melodic minor ascending)

Take the 7th mode of the C melodic minor, which is sometimes called the Super Locrian, or the Altered Scale. Here are the notes:

B C D Eb F G A

Now this scale can be thought of as having a flat second, an augmented second, a flat third and a major third! Pretty weird huh?

Now I'm not actually going to explain all the reasons why, but when you make the B Chord from this scale, you don't just take the 1, 3, 5, and 7. You actually take the 1, 4, 5 and 7 (B, Eb, F, and A), which makes a Dominant chord with a flat 5. If you also put the 9th in the chord, you use the C, which makes it a flat 9 chord.
so the chord is

B, Eb, F, A, C - B7b9b5

This is a very common jazz chord, and is frequently used in Minor 2-5-1 progressions such as:

F#min7b5 - B7b9b5 - Eminor(major7)

hmm.. Now that I think about it, this probably didn't help anyone. Maybe Jolly will like it.... :D
