The holes of the tremolo harmonica are divided into two upper and lower rows. Generally, when playing, the two reeds in the same hole sound simultaneously. Since the vibration frequencies of the two reeds are slightly different, simultaneous vibration will produce a phenomenon called "beat" in physics, which is manifested as a periodic change in the sound intensity, that is, the so-called "vibrato". The advantages of the tremolo harmonica are that the structure is simple and fixed, no complex skills are required, and the types and keys of the tremolo harmonica are complete. The tone is clear and loud, the volume is large, and it has strong penetration, which is a good choice for beginners.
