The Key of Bb major
Bb major is B♭ – C – D – E♭ – F – G – A.
Why this key
B♭ major is a horn player's key, not a guitarist's. Trumpets and tenor saxes are pitched in B♭, so a chart in this key puts them in C — which is why so many big-band and jazz standards live here while almost no guitar-written song does.
