Hichiriki is a seven-holed, double-reed woodwind instrument made of bamboo. It is approximately 18 cm long (7 inches). The first three holes are assigned to the left hand’s fingers and the last four to the right hand. There are also two thumb-holes on the back on the instrument.

The reed is made from ashi (mountain bitter bamboo). It is set in the head of the instrument and secured by a ring made from a folded strip of wisteria bark. The reed, being relatively large, can easily influence the pitch of the pipe. Sliding notes and tonal variation obtained by producing the same pitch on different fingerings is a feature style and a characteristic of the sound from this beautiful instrument.
The hichiriki, tuned to an A-430Hz, sounds one octave higher than written.
Pitches are playable by opening and closing the instrument’s nine holes with normal breathing. They are indicated as whole notes in Figure 3. The pitches shown in black are produced by a change of position of the reed in the mouth. By holding the reed deep in the mouth, a musician raises the pitch. For instance, the pitches on the second staff in Figure 3 are performed with the reed completely inserted into the performer’s mouth. On the other hand, the reed held in a shallow position lowers the pitch. Also weakening the lip pressure can lower the pitch a major second, while increasing it can raise the pitch up to a major sixth.

The hichiriki’s sound is extremely rich across its entire range. Figure 4 shows the spectra of its lowest and highest notes: F4 and A5 (written F3 and A4) and played ff. The spectrum of the F4 (in blue) shows energy on up to 55 partials while the spectrum of the A5 shows energy to at least its 25th partial. The frequency of the 25th partial is about 21,500 Hz, beyond the frequency range of human hearing, whose boundaries are universally set to 20-20,000 Hz.
Figure 4
Although the sound of the hichiriki is amazingly rich, it appears to have two weak frequency zones, one between C#8 and F8 (4343 - 5309Hz), and the other between E10 – G10 (10135 – 12066 Hz), as illustrated in Figure 5. These frequency zones correspond respectively to the 9th -11th (black arrows) and the 21st-25th partials (red arrows) of its B4, 482.65Hz.
