Keyboard instrument with the display device employing fingering guide

A keyboard instrument comprising:

• a keyboard;
• display means including a plurality of light emitting elements respectively corresponding to a plurality of keys on the keyboard and employing light emission;
• drive means for turning on/off the display means;
• and
• control means being responsive to a display instruction which sets a display time period for a note within a musical piece and to a light emission characteristic instruction which designates a light emission characteristic of the display means that is decided based on a time ratio of an ON period to an OFF period;
• wherein the control means allocates differing time ratios of ON periods to OFF periods to the display means to cause the drive means to turn on and off the display means a plurality of times during the display time period for a note according to the time ratios corresponding to the light emission characteristic decided and the differing time ratios allocated, so that position data for a key to be depressed and at least one set of another playing guide information are displayed at the same time with light emission characteristics different from each other.

A display device comprising:

• light emitting display means that includes a plurality of light emitting elements for emitting different colored lights;
• drive means for independently driving said light emitting elements that are selected;
• and
• control means for controlling said drive means so that, in consonance with a light emission characteristic instruction, a current is supplied to at least one of the light emitting elements and the current has a magnitude set to one of a plurality of predetermined values;
• wherein the control means, being responsive to a display instruction which sets a display time period for a note within a musical piece and to a light emission characteristic instruction which designates a light emission characteristic of the light emitting display means that is decided based on a time ratio of an ON period to an OFF period, causes the drive means to turn on and off the light emitting display means a plurality of times during the display time period for a note according to the time ratio corresponding to the light emission characteristic decided.

A keyboard instrument comprising:

• light emitting display means, individually provided for corresponding to a plurality of keys on a keyboard, that includes a plurality of light emitting elements for emitting different colored lights;
• drive means for independently driving said light emitting elements that are selected;
• and
• control means for controlling said drive means so that, in consonance with a light emission characteristic instruction, a current is supplied to at least one of the light emitting elements and the current has a magnitude set to one of a plurality of predetermined values,
• wherein the position data of the keys to be depressed is provided as a light emission characteristic instruction and at least one set of another play guide data is provided as a different light emission characteristic instruction;
• and
• wherein the control means, being responsive to a display instruction which sets a display time period for a note within a musical piece and to a light emission characteristic instruction which designates a light emission characteristic of the display means that is decided based on a time ratio of an ON period to an OFF period, causes the drive means to turn on and off the display means a plurality of times during the display time period for a note according to the time ratio corresponding to the light emission characteristic decided.
