This harmonica has a length of 1.4 inches (35 mm), but is a harmonica that has been precisely tuned to the C-tone. There are 8 sounds of 1 octave, so you can actually play many songs. This is a historic masterpiece of Hamamatsu, the city of musical instruments. The package uses prints from Kumayani Sensei Kumaya (Jiroshi Naotiger and Tiger Matsu) to complete the Ii Naotiga version.
