Hi, great web site.
I understand scales from playing the guitar for quite a few years and just got an alto sax in Eb.
I understand if a song is in the guitar or piano key of E I am actually playing in C#. on the sax, a minor third down from concert pitch.
But when I play along to tracks in E piano/guitar key, I find that I am playing in G blues on the saxophone.
Surely it should be C# blues.
It is as though I’m playing a minor 3rd up not down from concert pitch. It is the same for other keys e.g. D blues guitar is F blues on alto
How can this be? I know the backing tracks are in E, A or B.
