What does 撥の音も加えた gliss. mean? (in sheet music) I am a musician playing the Marimba. Because quite a bit of music for marimba is written by famous Japanese composers, occasionally I come across some Japanese text I would like to understand. In the piece "Two methods of Movement for Marimba", written by Toshimitsu TANAKA, there is, on the 6th page, a Glissando (moving with the sticks along all bars) with a star. At the bottom of the page, the star is printed again, this time with a note in Japanese. ![gliss]( ![note]( (Full images: glissando & note.) > _gliss._ I would be very grateful if someone could unveil the meaning of that sentence.

It reads: "[]{}[]{}[]{} _gliss_ ". This literally means: "The sound of drumsticks"-too "added to"-gliss, and in translation:

`Glissando complemented by the sound of drumsticks.`

It seems a bit rendundant, knowing that a Marimba would only allow for discrete glissando.
