Writing for Cello

Very few composers really knew how to write for cello. Only a handful of famous composers even composed famous cello pieces. This will be an effort to bring more information to composers and hopefully have more memorable repertoire.

Consider the cello as four instruments,

the A string is somewhat harsh in the low positions but in the high positions, it soars like a soprano. It's somewhat oboe-like

The D string is where most music intended to be played on the A string really is played as the notes are less harsh. 

The G string is the warmest and most soulful part of the cello, especially in a higher position. 

The C string is dark in the lower positions and almost comical up in the high positions, although it is scarcely heard. This string is quite like a bassoon along with the G string.

This effectively makes the cello the most resonant in G keys. Double stops with open strings are most abundant in keys around G. for example, D is the only key where closed position triple-stops can be used somewhat freely (only major and minor chords are shown)

Double stops

These usually cannot be used in quick succession, but if one note stays as a pedal tone, it is usable, either from a 3rd to a 5th or a 5th to a 7th within one position. Although sudden bursts are easier.

See Prokofiev Symphony-Concerto 2nd mvmt cadenza for examples (yes, I know it is one of the hardest pieces ever written for cello)

Harmonics on cello have the exact range as flute. note that only the distance between the two fingers matter: the range is the same for both touch-4 and touch-5.
