Xylophone combines the two words “xylos” meaning “wood” and “phonos” meaning “sound”.
It covers a whole family of instruments with wooden bars played with a mallet.
Made in Sweden by Auris.
Diatonic chimes
Diatonic is what "everyone" knows: c, d, e, f, g, a, h, c. (Please note h = b)
With the diatonic glockenspiels all songs can be played which are written in C major. So you don't need semitones (the black keys on the piano).
