Diatonic Hamonica

Also known as "blues harp", "harp", "short harp", or "standard 10-hole", the Diatonic harmonica is used in blues, rock, country, and folk, but can be used for most music styles.

Standard 10-hole. Comes in all 12 keys. Can play a complete 7-note major scale of the key of the harmonica. Bending certain draw and blow notes to obtain more notes from outside major scale.

Chromatic Hamonicas

Typically used in jazz and classical music, the Chromatic harmonica is found in all styles of music.

Has a button on the side. When the button is NOT used, you can play a normal major scale in the key of the chromatic. When the button is depressed, you have all the missing half-step notes in-between the major scale notes.

Tremolo Hamonicas

Primarily used for special effects, the Tremolo harmonica is used only to play the most simple melodies.

Diatonic models constructed with double holes. 8, 10, 12, or more sets of double holes, each set containing two reeds tuned to the same note, one tuned slightly higher than the other. Both reeds are blow or draw. When played, both will sound together and the slight difference in tuning creates a vibrating effect.

Octave-tuned

The Octave-tuned harmonica produces a strong and full bodied sound, but without the tremolo effect.

Similar to Tremolo models in reed layout and musical range. Each double hole has one reed tuned an octave apart from the other.
