The keyboard instruments evolved from which other instruments. One extelephone two harp, three flute, four wood blocks

Answer 1

Keyboard instruments evolved from several earlier instruments, particularly from stringed and percussion instruments. The most direct ancestors of keyboard instruments are:

1. Harpsichord: This instrument uses plucking mechanisms and has its roots in the early string instruments.
2. Clavichord: Similar to the harpsichord, it has a more intimate sound and is also related to string instruments.
3. Organ: While it involves pipes and wind, early versions had keyboard interfaces.

The other options you provided (extelephone, flute, wood blocks) do not relate to the evolution of keyboard instruments. Thus, the most accurate evolution would focus primarily on stringed instruments such as the harp and the various plucked string or struck string instruments that predate keyboard development.
