The 10 hole diatonic
harmonica is a transposing
instrument with various
keys.
Note that the chord
degrees are the same on all
the harmonicas.
Two main embouchures
• Tongue block
– The lips cover up to 4 holes.
– The tongue blocks all but the right hole (see

• Pucker or lip block.
– The lips cover all but one hole.
