This is one of the most well-known standards of all time. It’s usually done in Bb major/Gminor or G major/E minor, although when I was researching recordings of this tune I found recordings in C minor, A minor, D minor, Bb minor, B minor, F minor with an 8 bar vamp on F minor after the form (Chet Baker), F# minor, and C# minor.
We have included only recordings in G minor below. You may find recordings and a play along in E minor here.
