Abstract: A hand-pulled instrument, such as an accordion, typically has a sound post (or reed post) on which several reed plates are mounted. The reed plate usually has two oblong openings. Each opening relates to an elongated reed, which is widened at one of its two longitudinal ends for attachment to the reed plate. The opposite long end of the reed is not further fixed. The reed can be made to vibrate in a way that it partially swings into the associated opening. If air flows through the opening, in particular, due to a movement of a bellows of the hand-pulled instrument, such vibration can be generated, and in this way, an audible tone is produced. The reeds are usually attached to the reed plate with a rivet.

Abstract: A manual pulling instrument, in particular an accordion, comprising a first housing part comprising operating elements configured to be operated by a player with one hand to generate a note. The operating elements occupy a spatial area extending to a first boundary line on a first side and to a second boundary line on a second side opposite the first side, the second boundary line is further away from the bellows than the first boundary line, and the second boundary line has a concave curvature. The spatial area occupied by the operating elements extends in a plane which encloses an angle between 20° and 65°, with a center plane which extends symmetrically with respect to the bellows between the first housing part and the second housing part when the bellows is in a folded state.
