Method and apparatus for musical training

A non-transitory computer-readable medium having a set of instructions stored therein which, when executed by a processing device, causes said processing device to perform procedures comprising:

• presenting via a display, by said processing device, a pattern of music notes using a pitch-based representation;
• playing, by said processing device, said pattern of music notes in one or more absolute keys, where absolute key is defined by key, octave and scale;
• presenting via said display, by said processing device, absolute key changes in-place, as changes to the vertical locations of the visual representation of said music notes on said pitch-based representation, where the motions of said visual representations are relative to said pitch-based representation, which is vertically scrollable;
• receiving, by said processing device, an audio response;
• estimating, by said processing device, pitches of sounds within said audio response;
• and
• displaying via said display, by said processing device, the estimated pitches within said pitch-based representation,
• whereby, a user can visually see how pitches of notes change as keys change by letting the notes move vertically without scrolling the pitch-based representation, or how scales relate to each other either by scrolling the pitch-based representation vertically, which can be done manually or automatically, as absolute keys change or by performing an exercise that keeps the key constant during a subset of scale changes, so that the notes that change from scale to scale move vertically relative to a key that remains fixed relative to the display without the need to scroll the pitch-based representation.
