Yes, fingerings are the same. The Bass Clarinet will sound an octave lower in pitch.
Not exactly, bass clarinets have five keys at the bottom instead of four, but other than that I think it is the same.
Yes, the only thing different is that the A clarinet sounds a bit higher compared to the Bb clarinet Eric (Grade 8 clarinet player)
No, a bass clarinet, is way bigger than a Bb Clarinet (most common type), it touches the floor, and has the same fingerings but looks alot like the saxophone.
they are pretty different around B and C but the rest are almost the same as the notes over the break on the clarinet if that makes sense? :S
No. However the piccolo has the same fingerings as the flute.
