This is a list of instruments by Hornbostel-Sachs number , covering those instruments that are classified under 31 under that system. This category includes all instruments consisting of a simple string bearer and strings. An additional resonator may be present, but it is not integral, so removing it should not destroy the instrument - the resonator must not be supporting the strings.
3 : Instruments in which sound is produced by one or more vibrating strings (chordophones , string instruments ).
31 : Instruments which consist solely of a string bearer or a string bearer with a resonator that is not integral to the instrument
311 : Instruments with a string bearer shaped like a bar, or consisting of a sideways board (bar zithers )
311.1 : Instruments with a flexible or curved string bearer
311.12 : Instruments with string made from a different material than the string bearer
311.121 : Instruments with only one heterochord string
311.121.2 : Instrument has a resonator
311.121.22 : Instrument has a resonator that is attached
311.121.221 : Instrument does not have a tuning noose
311.121.222 : Instrument does have a tuning noose
311.2 : Instrument has a rigid and inflexible string carrier (stick zither )
311.21 : Instrument has a string carrier with one curved, flexible end (musical bow )
311.211 : Instrument has one resonator gourd
311.22 : Instrument has no curved or flexible end (true stick zither )
311.221 : Instrument has one resonator gourd
312 : Instrument has a string bearer made of a vaulted surface (tube zithers )
313 : Instrument has a string bearer made from canes tied together like a raft (raft zithers )
314 : Instrument uses a string bearer that is shaped like a board, or is the ground (board zithers )
315 : Instrument with strings stretched across the mouth of a trough (trough zithers )
316 : Instrument uses strings stretched across an open frame (frame zither )
This category includes musical bows , zithers and some keyboard instruments like the piano and harpsichord .
These instruments may be classified with a suffix, based on how the strings are caused to vibrate.
4 : Hammers or beaters
5 : Bare hands and fingers
6 : Plectrum
7 : Bowing
71 : Using a bow
72 : Using a wheel
73 : Using a ribbon
8 : Keyboard
9 : Using a mechanical drive
