Kumbengo for the song Bani Le
Another method is to use a representation of the kora bridge and strings, which allows the musician to see the interaction of the index finger and thumb on each hand for a better representation of kora playing technique. The main difficulty with this is that it is quite unwieldy and requires one to have blank sheets printed out to notate a piece.
Opening notes of Bani Le - showing strings
One can also use a form of tablature. Harald Lorenz’s Jaliya software uses its own form of tablature. Another method is to create a simple spreadsheet to show which strings are played. Each “beat” can be sub-divided into 4 (or 8) pulses and a number used to show which string is played, which finger or thumb is played with and the length and timing of the note. Even here, there is no standard convention on note numbering. Some people simply count from 1 to 10 (or 11) from the player upwards. Some prefer to count from the musician upwards for the thumb and from the kora downwards for notes played with the index finger.

However, most musicians will learn by listening and memorizing, albeit possibly helped by a mobile phone or recording device. This method of careful listening, repetition and rote learning is common to nearly all folk musics and has several advantages. Learning by listening carefully to a teacher allows subtle phrasing and technique to be acquired - things which cannot easily be expressed in written form. The ability to learn “by ear” allows the player to use recordings to learn new songs or variations, in the absence of a teacher.
