What is some good instrumental music?

In my Algebra cl, the professor plays instrumental music including some jazz, piano, and things of that sort. The great thing about it is that it has no words; it helps me concentrate on my work and makes the two hour cl great. The music isn't sad but relatively happy without getting unnecessarily fast. The piano isn't just piano but mixed with other things too. Yesterday, It wasn't mean to be taken this way, but a jazz song was on with heavy b that sounded somewhat like artistic music. Not at all music for perverts to listen to but when I heard it, it painted a picture of a woman's body in sensual, creative, artistic, and ual ways. Long story short, what are some great artists in these genres of music?
