So, I got up to a D# an octave above the two palm keys one the other day (the first time I seriously set out to learn altissimo). However, I haven't been able to get that high since. How exactly do I practice to improve my consistency in getting the notes out? Some days I get up to a C or so, and some days I can barely get out the F# a half step above the 3 palm keys :/ Scales? Arpeggios?
