Hi Johnny, I have another song in the works with a key change. ” Eres Tu”/Touch The Wind. Tenor sax key is F. Backing tracks start in E flat and later somewhere modulate to E. So I (tenor Sax) start in F and modulate to F sharp (F# G# A# B C# D# E# F#). Not my favorite Key
Oh I remember Eras Tu, yes that’s the most typical modulation; going up to the next half note…really helps to pick up the tune. Of course a lot of the time that type of modulation will take us up to a harder key, F to F# or G to G# etc
