Marimba

Small marimba (xylophone), made for a student. The wooden frame has an integral trestle stand. The twenty wooden bars have holes at both ends for suspension by two strings that also run through the small slats that separate the bars. All the bars except the topmost one have a wooden resonator of rectangular section tapering to a point, each with a small hole encircled by a black substance, with a buzzing membrane over the hole. The bars give a diatonic scale of one octave and one note above, plus five notes below. There are two cane beaters with heads each consisting of layers of wound rubber strips with an outer casing of smooth rubber.
