List of chordophones by Hornbostel–Sachs number

The Hornbostel-Sachs system of musical instrument classification defines chordophones as all instruments in which sound is primarily produced by the vibration of a string or strings that are stretched between fixed points. This group includes all instruments generally called string instruments (list) in the west, as well as many (but not all) keyboard instruments, such as pianos and harpsichords.

Simple chordophones or zithers (31)
Instruments which are in essence simply a string or strings and a string bearer. These instruments may have a resonator box, but removing it should not render the instrument unplayable (although it may result in quite a different sound being produced). They include the piano therefore, as well as other kinds of zithers such as the koto, and musical bows.

Bar zithers (311)
The string bearer is bar shaped.

311.1 Musical bows - The string bearer is flexible (and curved).

311.11 Idiochord musical bows - The string is cut from the bark of the cane, remaining attached at each end.

311.111 Mono-idiochord musical bows - Containing one string only

311.112 Poly-idiochord musical bows or harp-bows - Containing several strings that pass over some type of bridge.

311.12 Heterochord musical bows - The string is of separate material from the bearer.

311.121 Mono-heterochord musical bows - The bow has one heterochord string only.

311.121.1 Without resonator.

311.121.11 Without tuning noose.

311.21 Musical bow/stick - The string carrier has one rigid and one flexible end.

311.211 Instrument has one resonator gourd

311.22 True stick zithers - Round sticks which happen to be hollow by chance do not belong on this account to the tube zithers, but are round-bar zithers; however, instruments in which a tubular cavity is employed as a true resonator, like the modern Mexican harpa, are tube zithers.

Composite chordophones (32)
Acoustic and electro-acoustic instruments which have a resonator as an integral part of the instrument, and solid-body electric chordophones. The resonators and string bearers of these instruments are physically united, and they cannot be separated without destroying the instrument. This includes most western string instruments, including lutes such as violins and guitars, and harps.

Lutes (321)
The plane of the strings runs parallel with the resonator's surface.

321.1 Bow lutes - Each string has its own flexible carrier.
