Kimiko contributed to her social studies class blog about the Renaissance with the following paragraph.

The harpsichord was popular during the Renaissance. In some ways this instrument is a cross between a piano and a guitar. For example, it looks like a miniature grand piano, it has keys that are pressed, and it contains strings under a cover that can be propped up. However, the strings are not hit by a hammer-like object, as piano strings are. Instead, a harpsichord’s strings are plucked, like the strings of a guitar. Even the sound is a bit like a combination of piano and guitar.
