What is a 24 hole harmonica called?
About the Tremolo Harmonica
In Asia there are two main tremolo types, the 24 hole, used in China, the 21 hole, used in Japan and elsewhere. ... Both reeds sound when the instrument is played, producing a wavering tremolo sound (hence the name), somewhat like an accordian.
Is a 24 hole harmonica good for beginners?
no. As a kid, he may well have played a tremolo, but the note layout is considerably different from both a diatonic & a chromatic. If you want to get him something a little bit better/easier to play, take a look at a valveless 10/40 chromatic, they're fairly cheap, but a good starter chrom.
