A musical tone control apparatus comprising: (a) a hollow case (301); (b) a plurality of contacts (304) arranged within the inside of said hollow case; (c) conductive fluid (307) enclosed within said hollow case, said conductive fluid moving or flowing in response to an inclination of said hollow case so as to electrically connect between two contacts among said plural contacts, said hollow case generating an angle signal representative of said inclination of said hollow case in response to connected contacts; and (d) generating means (315) for generating musical tone control data which control a musical tone to be generated based on said angle signal.

Claim 85

A musical tone control apparatus according to claim 69 wherein said contacts (304) are arranged into a matrix.

Claim 86

A musical tone control apparatus according to claim 69 wherein said musical tone control data represent tone parameters such as a tone pitch and a tone volume of the musical tone.

Claim 87

A musical tone control apparatus according to claim 69 wherein an inclination detection of said hollow case (301) designates a specific tone parameter among said tone parameters.
