Instrument Families
Strings, winds, percussion, and keys: the criteria that group instruments together and what the members of each family have in common.
Strings, winds, percussion, and keys make up the basic vocabulary of any conversation about instruments. Grouping is more than tidiness: a family reveals the physical principle that produces the sound and helps you predict how the instrument behaves, from the attack of a note to the reach of its range.
Here you will find the logic behind the classification systems, from the criteria used by museums and organology treatises to the borderline cases that challenge the categories, such as the piano, which is at once a keyboard, a string, and a percussion instrument. The matching quiz explores exactly those borders.
