I play the clarinet and bass clarinet as a hobby
I have developed an interest in the shakuhachi since 2010:
Now:
Shakuhachi notation has roots in hitoyogiri notation
Shakuhachi is present in Japan during the Nara period (710-794 CE)
First documented notation system in 1608 in the Tanteki Hiden Fu
(Secret pieces for the short flute)
1664: Shichiku Shoshinshu (Self-help guidebook on musical instruments)
Hitoyogiri notation with 13 syllables (katakana) representing different notes:
fu フ i イ ya ヤ chi チ ho ホ u ウ e エ
ri リ hi ヒ kan 神 ta タ ru ル shō 上.
Some shakuhachi players changed the hitoyogiri notation and used:
fu フ ho ホ u ウ we ヱ ya ヤ i イ
for the basic fingerings of the shakuhachi
Fu Ho U notations are used in some schools:
Tehodoki Reiho, Kichiku Ryū - Justin Senryū


ro ロ tsu ツ re レ
instead offu フ ho ホ u ウ
These Ro Tsu Re notations are now the most prevalent:
Notation ➛ fingering
Lines indicate duration by their length
There is no tempo, the sound is stretched through time according to:
Synchronization of the players requires a more precise timing
Omote marks on the right
Ura marks on the left
Single line: twice as short notes
Triangles indicate beats where no note starts
Notes fill in the space between marks:
the first and the third ヒ do not have the same
duration although they have two omote marks!
Another example: Chidori no Kyoku
This notation of Chidori no Kyoku was written by Miura Kindō, who studied with Araki Kodo II
and Uehara Rokushirō, and published by the Chikuyūsha guild of Kinko-ryū.
It differs slightly from the notation of Araki Kodo II, III and IV.
タコ足 Tako ashi
(octopus legs)
Seien Ryū
モ style
Kyū Myōan notation
モ makes the duration longer
Each mark under モ makes it even longer
A vertical line beside notes makes them shorter
Compared to Kinko notation
Durations
Shakuhachi notations indicate fingering
Variations in pitch can be shown by vertical lines
or by indications such as 引き (hiki: pull)
Pitch of the “natural” notes of a 1.8 shakuhachi shown on a piano keyboard:
There are missing pitches...
The pitch of the basic notes is changed by the meri or kari
position of the embouchure, and by partially closing holes
There are three kinds of meri: small, normal, and deep
Basically:
Examples:
However:

Neumes
(Gregorian chant
in Western Europe)
Ekphonetic notation
(Gregorian chant
in Byzantium)
When you start and end in the range ri Ĥ/ha ɴ to tsu ě,
you change octave, else you stay in the same octave.
For instance
Evolved in various monasteries for the notation of Gregorian chant
Converged towards the modern Western notation through exchanges

Western notation uses dots placed on a five line staff
The pitch of the notes is given by a key, we consider only the treble key here
Natural notes of a 1.8 shakuhachi:
Variations in pitch are indicated by sharps (♯), flats (♭), and naturals (♮)
Durations are indicated by the shape of the note.
Bars group units of time indicated by a time signature
Default pitch alterations are indicated by a key signature
Western notation does not always indicate pitch
Some families of instruments exist in different sizes,
so a given fingering does not yield the same pitch on all instruments
Clarinets
Saxophones
In Western music vocabulary, an instrument is in X if
the fingering for C on this instrument produces the pitch of X
What is the fingering of C on a shakuhachi?
“Normal” 1.8 shakuhachi: the pitch of C is obtained with ɱ (ri)/ɴ (ha)
⇒ ɱ/ɴ is considered as the fingering of C on the shakuhachi
Therefore:
Lowest note (ro)
When specifying shakuhachi pitch, it seems safer to give
both the expected pitch of ro and the length of the shakuhachi
Prefer “a 2.0 shakuhachi, ro = C” to “a B flat shakuhachi”, or “a C shakuhachi”
For 1.6

Example: Chidori no Kyoku with flute players
Reading a notation is not playing the style of a school
Reading several notations helps playing in various circumstances
Being able to read Western notation opens opportunities
outside the domain of traditional Japanese music
When playing Western notation:
