George and Ira Gershwin wrote "Someone To Watch Over Me" in 1926 for a Broadway musical called "Oh Kay," and Gertrude Lawrence's heart-rending rendition of the ballad made it an instant hit. It's a favorite for vocalists. In the AABA form, the A section of the chorus features chromatically rising and falling bass lines. In this key-of-A version, it goes down (looking just at the bass notes: D#, D, C#, C, B, Bb) and comes up (Bb, B, C#, D, D#, E). The beautiful introductory verse is included here, and it's like a song in itself.
