The double bass is classified as both a chordophone and an idiophone because of the different ways it can be played to produce sound, according to the Hornbostel-Sachs system of instrument classification.1
- Chordophone: The double bass is primarily considered a chordophone because it features stretched strings that vibrate to produce sound when bowed or plucked.21
- Idiophone: It is classified as an idiophone when the player strikes or slaps the body of the instrument itself. In this context, the sound is generated by the vibration of the instrument's material rather than by the strings under tension.31
Many musical instruments can be categorized into multiple classes depending on the specific technique used by the performer, as the classification system is designed to organize instruments based on their physical properties and methods of tone production.1
