I think I have done my homework here, but let's see. I have searched for anything on doodle tonguing with no result. I think I remember Clark Terry commenting on this somewhere (UTube?). Anyway my question is: Is this just the jazzer's version of double tonguing using doo for the first part of the attack and le for the second to accomplish a fast attack for rapid improvs? I assume the fast passages in Freddie Hubbard's improvs are examples? Anyone know about doodle tonguing?
