The video below has a blues is in F concert that you can play along with.
So that means G for tenor saxophones and soprano (they’re in Bb) and D for alto saxophones & bari saxophones (they’re in Eb).
A basic blues uses the I chord IV chord and V chord.
You can use the blues scale over the whole chorus- some notes will work better than others in different spots, so be aware and keep your ears open.
The G blues scale, that you would play on tenor/soprano sax for this, is:
G – Bb – C – C# – D – F – G
The D blues scale, that you would play on alto/bari sax for this, is:
D – F – G – Ab – A – C – D
So try playing around with it!
