Posture and Breath Control

Posture And Breath Control

  • Hold the harmonica with your left hand and blow into it with your right hand.
  • Form a tight seal around the mouthpiece with your lips.
  • Keep your head upright, shoulders relaxed and feet firmly planted on the ground.
  • Exhale gently and evenly and adjust the pressure of your breath depending on the desired sound.
  • Take short, shallow breaths as you play.
  • Use your abdomen to control the breath, not your chest.
  • Make sure to keep your breath consistent and steady.

Tongue Blocking and Single Notes

Tongue Blocking And Single Notes

  • Place the harmonica in your mouth so that the blow reed plates are on your left and the draw reed plates are on your right.
  • Form a tight seal between your lips and the harmonica.
  • Press the tip of your tongue against the roof of your mouth, blocking all of the holes.
  • Breathe out to blow air through the blow reed plate and listen for the note to sound.
  • Breathe in to draw air through the draw reed plate and listen for the note to sound.
  • Repeat with different notes until you become comfortable with the technique.

Double Notes

Double Notes
The diatonic harmonica consists of two sets of reeds, one set in the lower octave and the other in the upper octave. Double notes are created by inhaling and exhaling simultaneously. This technique enables the player to play two notes at once and create a fuller chordal sound. To play double notes, the player should inhale and exhale at the same time, using the same breath. This will create a vibratory sound that is made up of two notes in both the lower and upper octaves. Double notes can be used to create a fuller sound and add color to the harmonica.

Slurs and Bends

Slurs And Bends

  • Slurs are two or more notes that are played in one breath.
  • Bends are notes that are bent up or down to create a new note.
  • To play a slur, blow into the harmonica, using the same hole for both notes.
  • To play a bend, press down on the reed and blow into the harmonica at the same time.
  • The amount of bend can be adjusted by adjusting the pressure on the reed.
  • It can take practice to get the hang of playing slurs and bends.

Playing Chords

Playing Chords

  • Hold the diatonic harmonica with one hand and blow in the holes with the other hand.
  • To play a chord, press the blow and draw notes together.
  • Press all the necessary blow and draw notes and hold them together, this will create a chord.
  • The same chord can be created by pressing the draw and blow notes one after the other.
  • The chord can be held as long as needed.

Playing Melodies

Playing Melodies

Melodies on the diatonic harmonica can be played using bends, overblows, and overbends. To play a melody, begin with a basic blow or draw note, and then use bends, overblows, and overbends to change the pitch of the note.

Technique Description
Bends Bending is a technique used to lower the pitch of a note. To bend a note, blow or draw the note, and then press the reed down with your tongue or lip while blowing or drawing. This will lower the pitch of the note.
Overblows Overblowing is a technique used to raise the pitch of a note. To overblow a note, blow or draw the note, and then press the reed up with your tongue or lip while blowing or drawing. This will raise the pitch of the note.
