You are probably familiar with the melodeon. However, have you ever seen a melodica? This is like a normal keyboard instrument but instead of using batteries, the sound is powered by the musician blowing through a mouthpiece. The instrument is cheap to buy and maintain and so is very popular in schools in Asia. The students can learn how to play it very quickly. The melodica is known by various names, often at the whim of the manufacturer. Melodion (Suzuki), Melodika (Apollo), Melodia (Diana), Pianica (Yamaha), Melodihorn (Samick) and Clavietta are just some of the variants.
