I have a King Zephyr Special alto
My bad...although the fingering chart from Better Sax does not show the octave key being used for palm keys D,Eb and F,nor does it refer to them as top keys.
Aha!!!Thank you Halfers. So even modern altos can`t play those notes in tune w/out the octave key?It seems like it could be a useful sequence in the middle register.
It never ceases. There's always more.I have a LOT to learn...thanks for all the info.
