A music training method comprising steps of

• providing a numerically notated sheet comprising a sheet having a plurality of rows, each row displaying a plurality of numbers, each of said numbers being an integer having an absolute value from 1 to 7 and corresponding to a key of a keyboard, and said integers corresponding to keys to be played for a musical composition;
• and
• providing a numerical keyboard chart,
• said numerical keyboard chart comprising a sheet having a face and magnetic backing, a sheet width and a sheet height,
• the face of the keyboard chart displaying a plurality of rectangles corresponding to a plurality of keys on a keyboard, said keys on the keyboard including naturals and accidentals,
• the sheet width being no greater than a width of the keyboard,
• each rectangle having a rectangle width about equal to a width of a key of the keyboard, and
• each rectangle being separated from an adjacent rectangle by a space, and
• the plurality of rectangles being configured to align with the keys of the keyboard,
• and the sheet height being between 1 inch and 6 inches;
• and
• said numerically notated sheet, and
• the rectangles corresponding to naturals have a first appearance, and the rectangles corresponding to accidentals having a second appearance, and
• each rectangle corresponding to a natural displaying a number, said number being an integer having an absolute value from 1 to 7, and
• a plurality of magnetically attachable indicia, said attachable indicia being removably attachable to the face of the numerical keyboard chart;
• and
• playing the key corresponding to each numbered rectangle on the keyboard chart as indicated by each number on the numerically notated sheet.
