Does anyone know of a tool, online or elsewhere, that will:
a) if you give it the notes, it will tell you the name of the chord. like if you give it "C-E-G-C-D-E" it will give you "C9"
b) identify potential scales. like if you give it "C-D-E-G-A" it will come back with "C Major" "G major" and "F major" "A minor" etc.
anyone know of something like that?
