Shaahin Mohajeri believes that 96-EDO (96 equal divisions of octave) is a good system for intervallic structure of Persian music with more accurate estimation than ali naqi vaziri's 24-EDO system. Now, He is working on a microtonal notation system based on 96-EDO and on a model for tuning systems classification based on divisions of octavic or nonoctavic musical scales and systems.
Microtonalist Aaron Krister Johnson in his interview with tokafi Called him as a very talented individuals from the Middle East.
Some of his tuning models and sclaes are being refered in scala , a powerful software for experimentation with musical tunings. His musics are composed in different modal , tonal and atonal microtonal spaces and also shows polymicrotonality as a way to relate different microtonal systems to each other. He is also working on a new rhythmic system named as "Microrhythm" based on time intervals defined in new rhythmic systems.
He began studying tombak under supervision of Nasser Farhangfar, master of tombak, but His Studies of tombak sounding and fingering, tombak musical analysis and his arrhythmic musical ideas have led him to a different musical world of music , tombak and tombak playing.
He composes music for solo of tombak and tombak ensemble with different microtonal tunings , ranging from traditional to his personal style.
He is working on a new musical notation system for tombak as a result of acoustical parameters and a system of fingering classification for this drum .
On 23 Dec 2006 Shaahin mohajeri lectured on tombak history, organology,acoustics and tunable tombak of Dr.Hossein omoumi in the Tehran Conservatory of Music.
