Keyboard musical instrument displaying depression values of pedals and keys
A keyboard musical instrument supports lessons in practicing musical performance on a keyboard to allow users to learn musical performance expressions. In accordance with a teacher's model performance, performance data representing operations of keys of the keyboard, pedal depression data representing operations of pedals, and damper position data representing positions of dampers in action mechanisms are created and recorded on recording media such as flexible disks. When a student plays the keyboard musical instrument, the performance data, pedal depression data, and damper position data are reproduced by means of the recording media, so that they are displayed on the screen of a display, wherein the prescribed keys to be depressed are sequentially displayed in a piano roll form based on the performance data, and wherein depression values of the pedals and positions of the dampers are displayed based on the pedal depression data and damper position data.
1. A keyboard musical instrument comprising:
a display divided into first and second display sections;
the first display section comprising a keyboard display section for displaying operation states of keys of a keyboard;
the second display section comprising a mode-selectable display that alternately displays (a) an action display for providing a visual representation of keyboard action and (b) a pedal display section for displaying operation and depression of pedals; and
a control device for controlling the keyboard display section to display the operation states of the keys of the keyboard based on performance data representing the keys of the keyboard to be sequentially depressed, and for controlling the pedal display section to display the operation states of the pedals based on pedal depression data representing depression values of the pedals.
2. A keyboard musical instrument according to claim 1 , wherein the performance data are created to indicate fingering guidance for sequentially designating the keys to be depressed.
3. A keyboard musical instrument comprising:
a keyboard display section for displaying operation states of keys of a keyboard;
an action display section for displaying relative positions of selected parts of action mechanisms including intermediate positions, which transmit operations of the keys to strings in action mechanisms; and
a control device for controlling the keyboard display section to display the operation states of the keys of the keyboard based on performance data representing keys of the keyboard to be sequentially depressed, and for controlling the action display section to display the operation states of the selected parts of the action mechanisms in a time-series manner.
4. A keyboard musical instrument according to claim 3 , wherein the performance data are created to indicate fingering guidance for sequentially designating the keys to be depressed.
5. A keyboard musical instrument according to claim 3 , wherein the selected parts of the action mechanisms are dampers for damping vibrations transmitted to the strings in the action mechanisms, so that the action display section displays positions of the dampers in a progression of a musical performance.
