This perfect beginner's harmonica plays a full 8-note octave with only 4 holes. Each hole produces 2 different notes: a blow note and a draw note. The large and widely-spaced holes make it easy to produce clear, single tones on the very first try. As a bonus, the names of each note and their position in a musical scale are printed right on the top, for easy reference. Just 'lift, pucker and blow' for music at your fingertips! HOH-S502
