Hold the music in one hand with your thumb over the bottom and index finger over the top and back of the instrument, so that you can place your mouth and lips completely over the holes. The numbers stamped above the holes must face upwards.
Shape your lips into a loose shape ‘O’. Choose a hole in the harmonic and place it against your lips. Moisten your mouth and lips to help form an airtight seal with the instrument.
Blow into a hole to play a single note. If more than one note sounds, adjust your lips. Practice until you can play the single with consistency.
Pull (inhale) the accordion into the same hole to play the second note, adjusting your lips if necessary. Practice blowing and pulling on the hole until you can play the two notes without adjusting your lips.
Move the accordion over your mouth to the right until the first hole (lowest note) is against your lips. Blow and pull into the first hole. Continue to the second through the 12th hole to play the full scale. Play slowly, adjusting your lips as needed. The goal is to play the two notes on each hole clearly.
Tips and warnings
Playing a 24-hole accordion involves the same principles as playing any harmony. The standard harmonica consists of a series of holes, with each hole containing a single roll. An accordion boiler is a thin metal tab that vibrates and produces sound when air is blown into the instrument. Twenty-four hole harmonics have an upper and lower row, each row with 12 double holes. When you blow into a hole, both vibes vibrate, giving a fuller sound than single-line harmonics.
