Abstract
An input support method is provided for use in an input support apparatus that supports input of a music note. The method includes: controlling a display unit to display a pitch-time plane that includes a pitch-axis and a time-axis, a chord sequence that is associated with the time-axis of the pitch-time plane, and a pointer that indicates a position on the time-axis along the chord sequence; identifying constituent music notes that form a chord corresponding to a display position of the pointer along the chord sequence; and controlling the display unit to display areas on the pitch-time plane, each displayed area indicating a corresponding one of the identified constituent music notes, differently from other areas on the pitch-time plane.
Claims14
A method for use in an input support apparatus, the method comprising:
- controlling a display unit to display a pitch-time plane that includes a pitch-axis and a time-axis, a chord sequence that is associated with the time-axis of the pitch-time plane, and a pointer that indicates a position on the time-axis along the chord sequence;
- identifying constituent music notes that form a chord corresponding to a display position of the pointer along the chord sequence;
- and
- controlling the display unit to display areas on the pitch-time plane, each displayed area indicating a corresponding one of the identified constituent music notes of the chord, differently from other areas on the pitch-time plane,
- wherein the controlling of the display unit to display the chord sequence includes controlling the display unit to display the chord sequence based on chord progression information that indicates multiple chords included in a music piece in an order that is in accordance with progress of the music piece, and
- wherein the identifying of the constituent music notes includes:
- (i) identifying a chord that corresponds to the display position of the pointer in the music piece according to the chord progression information and (ii) identifying constituent music notes that correspond to the identified chord.
An input support apparatus comprising:
- a display controller configured to control a display unit to display a pitch-time plane that includes a pitch-axis and a time-axis, a chord sequence that is associated with the time-axis of the pitch-time plane, and a pointer that indicates a position on the time-axis along the chord sequence;
- and
- an identifier configured to identify constituent music notes that form a chord corresponding to a display position of the pointer along the chord sequence,
- wherein the display controller controls the display unit to display areas on the pitch-time plane, each displayed area indicating a corresponding one of the identified constituent music notes of the chord, differently from other areas on the pitch-time plane,
- wherein the display controller is configured to control the display unit to display the chord sequence based on chord progression information that indicates multiple chords included in a music piece in an order that is in accordance with progress of the music piece, and
- wherein the identification of the constituent music notes includes the identifier configured to:
- (i) identify a chord that corresponds to the display position of the pointer in the music piece according to the chord progression information and (ii) identify constituent music notes that correspond to the identified chord.
