A muffler mechanism for a piano includes at least one axially rotatable muffler pipe arranged below and extending over an array of strings and a flexible muffler coupled to the muffler pipe and registable at an operative position suited for damped performance, thereby enabling a simple construction, a reduced mounting space and stable and reliable damping effect without deformation even after long use.

DETAILED DESCRIPTION It is the object of the present invention to provide a muffler mechanism of a simple construction and requiring reduced space for mounting without impairing its damping effect.
In accordance with the present invention, at least one axially rotatable muffler pipe is arranged below an array of strings whilst extending in the width direction of a piano and a muffler is attached to the muffler pipe for movement between an inoperative position for normal performance and an operative position for damped performance which is located between the array of the strings and an array of hammers.
