The Shakuhachi is the simplest of musical instruments, but in the hands of a master musician, the flute is capable of an immeasurable variety of dynamics and timbre. The long diminishing notes, coupled with unusual techniques and almost inaudible grace notes, produce beautiful, haunting melodies. Phrases are played to the full ability of one's breath. The sound has a distinct Zen flavour, depicting with skilful simplicity the beauty of nature.
One very striking feature of shakuhachi playing is the wonderful use of movement and physical gesture in performance. This is because fine pitch and timbrel control is achieved through the repositioning of the blowing edge against a consistent embouchure. Moving the flute in space also provides the musician with visual and tactile cues to monitor these finer parameters of sound control. Lateral movements of the head, tilting of the flute and head are all common techniques seen in shakuhachi playing. These movements are interpreted from the score as fingering patterns written to sound another pitch; tilt and head movements are then used to compensate the pitch resulting in specific timbrel and dynamic effects.
Unlike the Western flute, the shakuhachi appears basic and economical. In reality, first impressions can be very deceiving. Five large open holes allow for cross, half, quarter fingerings for accurate microtonal control of pitch. In fact, several ryu (schools) of shakuhachi have categorised up to 60 divisions of the octave so tuning control now becomes a life journey, not a constraint.
Points on getting a strong tone
When you play Shakuhachi you ideally want an embouchure that is fixed like a recorder mouthpiece, so the high octave, and the low, can be played easily, without having to change the lip shape for each note played. (Holes on the shakuhachi are numbered from the bottom up, so the back hole is 5)
P.S. With a poor shakuhachi this is not possible as the lower notes will flip to the high octave, or warble and burble with the 'wolf' notes. This is one reason people do not play strongly, and the pitch of notes will be too low.
