Lyrics:

[Stevie Wonder]
I was sitting in my classroom the other day
Playing my harmonica in a mellow way
Some teachers seemed to have gathered 'round
Trying to figure out what I was putting down

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

[Harmonica solo]

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

[Instrumental break]

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

[Instrumental break]
