Second chorus you've forgotten what you did the first chorus. Yeah. Well, you have to store up all these tunes in your head. You have to like it. You've got to like those songs.  Irving Berlin, you know how many songs Irving Berlin wrote? More than anybody. I think I know them all, just because I was around when they came out, a lot of them. Even "Alexander's Ragtime Band" that was way before my time but you learned that right away, you know. It's a very simple song. Any fool can play it though [hums]. 1-4-5, it's all based on. The rock `n roll has those three chords, 1, 4 and 5. You learn those three chords you can play almost anything, until you get into Cole Porter. George Gershwin gets a little more, you know, Harold Arlen, it gets a little more sophisticated and you've got to learn all those other little side turns. Jerome Kern, "The Song Is You. " I mean it separates the men from the boys when you learn the release to "The Song Is You," it goes into all kinds of strange levels, you know? You start in C and then you go into E and you go into G# minor and, you know. So it helps to study all those chords. Study harmony.  Study composition, the way chords are constructed. Bass lines, and the little cello line.  The melody and the bass line, and then one other line inside there, the tune is constructed on those three lines. The melody and the bass, even in Beethoven or Bach, that's still a fundamental that goes through any music. You have the melody and then have the bass, and then you have all the stuff in between, that's just the icing on the cake. But the fundamental thing is the bass line and the melody. Am I making any sense at all?
