I Call It Pretty Music but the Old People Call It the Blues Lyrics

I was sitting in my classroom the other day
Playing my harmonica in a mellow way
Some teacher seemed to have gathered ′round
Trying to figure out what I was putting down

I called it pretty music
But the old people call it the blues

Ain't that pretty mad

They were looking at me sitting there all alone
Mumbling to each other in a real low tone
I couldn′t figure out what they were saying
They couldn't understand what I was playing

But I called it pretty music
But the old people call it the blues

Ain't that pretty mad

Well, I called it pretty music
But the old people call it the blues, oh yeah

I called it pretty music
But the old people call it the blues
