Flattement 
(Microtone Trill) Fingering Chart for Recorder
First 
Octave: C4 to B4 / F4 to E5
This 
fingering chart includes flattement fingerings, which are fingerings designed 
for finger vibrato, much like a trill or tremolo but with microtone intervals 
(less than a semitone) instead of larger intervals. Holes 
to be trilled are indicated in  red. When 
more than one hole is to be trilled, the holes should be simultaneously covered 
and simultaneously uncovered, unless the description says to alternate covering 
and uncovering the keys. The fingerings apply to all sizes (sopranino, soprano, 
treble/alto, tenor, bass, and great bass) of both English and German recorders 
unless specified otherwise. Note that the fingerings apply to the lower set of 
notes for C instruments (soprano, tenor, and great bass) and to the upper set 
of notes for F instruments (sopranino, treble/alto, and bass).
