On this page the multiphonics are sorted into series showing all the "lower" fingerings combined with each “pseudo-register” fingering - e.g. "R" (register key closed, thumb-hole open) combined with the fingering for low E, F, F# etc. Space is left in each series where the fingering didn’t produce a dyad.
Dyads that speak extremely softly or are exceptionally difficult to produce are notated with crossed note-heads.

Most of these multiphonics are hard to produce, not flexible and not tested by anyone else except me – it’s possible many of them won’t work or will have different results for other players.
