PERCUSSION/KEYBOARDS/HARP INSTRUMENT WRITTEN SOUNDING NOTES Crotales Flexatone Pitches are obviously approximate. Glockenspiel Tubular Bells Vibraphone Xylophone Note that the given range is standard. However instruments do exist that are extended even as much as an octave in either direction. An extension down a third or a fourth is the most common such extension, but even so it is unusual. Check availability before writing for such instruments. (Thanks to Lennart Westman for this note). Marimba Timpani (set) Each individual drum in a set of timpani has a range of a fifth. Check the timpani pages for further information. Piano Some pianos extend downwards by a further 5th.
