This is a wonderful harmonica that is very easy to look at. It is a tremolo harmonica, which is used for classical, gospel, and folk songs. It comes with many benefits, including it's surprisingly low cost. The tremolo sound is produced by stacking one reed on top of an other and tuning one slightly off, so the two sounds "fight" and create a sound similar to a warble (or when you make a 1/2 step trill on your chromatic). It's available in all 12 keys. It comes in a small pouch with small booklet of common songs. It is very powerful, not noisy. It is longer than a 4" diatonic. Drawbacks: It has a plastic comb. It's highest notes can annoy an audience. It smudges very easily.
