KM Works (operated by Kohei Mikuni) will officially launch "YUBi-RAKU," an AI tool for optimizing clarinet fingerings, on July 1, 2026 (Wed). This tool is a web application that automatically suggests the smoothest fingerings for演奏 by considering the context of the input phrase. Under the supervision of clarinetist Chikanon, a dedicated fingering search mode for trills and tremolos is also included.

Background of Development

While countless "alternative fingerings" exist for the clarinet, many players in school ensembles or orchestras without specialized instructors resort to using only the basic fingerings found in method books. Fingering charts in method books often make it difficult to smoothly play fast passages or phrases with many slurs. Furthermore, many aspiring players cannot afford professional lessons due to budget, location, or networking constraints.

"YUBi-RAKU" was developed with the aim of solving these fingering selection challenges using the power of AI.

Main Features

1. Phrase Fingering Optimization Function

Simply input a phrase, and the AI will suggest the smoothest fingerings, considering the preceding and succeeding notes.

2. Trill & Tremolo Fingering Mode

Easily search for trill and tremolo fingerings, which are often not found in method books. Includes fingerings that provide excellent tone and intonation, devised by clarinetist Chikanon (for extremely high registers or tremolos with wide pitch intervals, AI-devised fingerings will be displayed).

3. Share Function

Instantly share suggested fingering results with your bandmates.
