(Faber Piano Adventures ). Bettyian Roulade is an advanced solo flute piece premiered at the 2012 National Flute Convention in honor of Betty Mather, the famed flute pedagogue. The word "roulade" originates from the French word "rouler" that means "to roll." This piece features "rouladian" passages that combine overblown arpeggios, tremolos, and harmonics.
