Tip 1: C# Fingering
Lowers the sharp C#2 and raises the low C#3.
“Should be practiced and used as a primary, not alternate, fingering for piccolo.”
Jan Gippo, solo piccoloist, St. Louis Symphony
Tip 2: F#3 Fingering
Little finger of right hand is off.
Tip 3: G-A for piccolos with a split-E
“This trill needs a kick to get it started. Begin the trill by fingering G3, then lift first finger left hand and trill as shown.”
Morgan Williams
Tip 4: G-A trill for piccolos without a split-E
For piccolos without a split-E mechanism, kick off with the G3 fingering.
