Studying the score of Prokofiev's 4th I saw this instrument:
Clarinetto Piccolo stated at the beginning of the scorelines
but in the instruments list at the very beginning of this scorebook:
Clarinet in Eb
2 Clarinets in Bb
Bass Clarinet in Bb
is this Clarinetto Piccolo the same as Clarinet in Eb?
Even in my book of Orchestration I can't find a definition of this instrument (=Clarinetto Piccolo).
