Tremolo harmonicas are a type of harmonica, distinct by having two reeds per note. In a tremolo harmonica the two reeds are tuned slightly off a reference pitch, one a bit sharp and the other a bit flat.
This gives a unique wavering or warbling sound created by the two reeds being not exactly in tune with each other and difference in their subsequent waveforms acting against one another. Folk music and traditional harmonica tunes are commonly played using a tremolo harmonica.
