My Favorite Altissimo Fingerings:

Please note that these are the fingerings I personally like, and may not work for all horns or players. Many of them are considered "standard" although I developed them on my own, before I knew they were. All fingerings are for alto, unless specified. - Jason DuMars

High F#:

Finger the standard auxiliary front F key (first finger of left hand on the aux F and 2nd finger on the C key) -- add side Bb

High G: (No multiphonic)

Finger the auxiliary front F key (first finger of left hand) without holding down the C key, add side Bb and right hand F finger.

High G: (with multiphonic)

B and G in the left hand, F and D in the right

High G#: (overblowing will get a weak multiphonic)

Same as G (non-multi) above, only lift right hand F key

High A: (No multiphonic)

Same as G# (non-multi), add C trill side key

High A: (multiphonic)

A and G of left hand with E and D in the right

High Bb: (non-multi)

Finger middle D, lift left hand B finger, add D palm key

High B: (No multiphonic)

A and G in left hand, F and D in right, add D and Eb palm keys

High B: (Multiphonic)

Finger middle D and overblow the harmonics of the note

High C: Option 1

B and G in the left hand with F and D in the right

High C: Option 2

Finger standard high C (C + octave key) and add D and Eb palm keys

Notes:

The non-multi versions of these fingerings were ones I found that worked very nicely for scale patterns. They are not necessarily as handy when doing intervalic leaps. The altissimo C option 2 is not as reliable as option 1, but is nice because of the Octave-Minor 3rd possiblity. High B (multi) works great on tenor, and so does the option 2 C. Good luck! Stay tuned for my STB fingerings…
