ABSTRACT:
A wrist training assembly that is intended for use by releasably clamping it to a piano keyboard with a predetermined amount of clamping force. The assembly is releasably locked in place but the clamping and locking functions are separated so that the finish and structure of the piano are protected. The assembly is rapidly installed and uninstalled from a wide variety of pianos without alteration to either the pianos or the assembly. The keyslip of the piano has a first face that faces and is spaced from the keys to define a channel between the piano keys and the first face. A training bar member is mounted to a clamping unit so that it extends a predetermined distance from and generally parallel to the channel. Preferably, two spaced apart mounting hook members are pivotally mounted to the training bar member and adapted to engage with the first face of the keyslip. The clamping unit is moveably mounted to the training bar member and resiliently biased towards the mounting hook member by a predetermined amount of spring tension. The amount of spring tension is pre-selected and is not adjustable by the user. The clamping unit includes a bearing face that is opposed to the mounting hook members and is adapted to bear resiliently against the piano. The amount of spring tension is pre-set at such a level that the bearing face will not mar or distort the piano structure or finish. Once the bearing face is engaged with the piano under the urging of the predetermined spring tension, a releasable detent member is actuated to lock the clamping unit relative to the training bar member and the associated mounting hook members.
