Etymology
“Wood” and “sound” describe music produced by striking wooden bars with hammers. The early English rendering “music-sticks” captures the same concrete image.
In context
That might just be the xylophone. This percussion instrument is made up of wooden bars of different lengths arranged side by side. When you strike these bars with mallets, they produce a delightful sound.
