Disclosed are a spiral curve type music sheet in which different notes are displayed at different positions on a spiral curve based on the pitches of notes, and an apparatus and method for providing a spiral curve type music sheet. The apparatus for providing a spiral curve type music sheet may include a memory configured to store a spiral curve type music sheet in which different notes are displayed at different positions on a spiral curve based on the pitch of the note and note data, and a processor configured to determine the note symbol position related to the note data on the spiral curve in the spiral curve type music sheet based on the frequency of the note data.

A sheet music display device, including a display unit constructed to be transparent, a stand assembly, including a body disposed on at least a portion of the display unit, and an illumination unit longitudinally disposed on at least a portion of the body toward the display unit to illuminate the display unit, such that the display unit renders a sheet of music thereon, a pole perpendicularly disposed at a first end away from the stand assembly with respect to a direction, and a base disposed on at least a portion of a second end of the pole to support the pole thereon.

A music learning aid, comprising: a first rotatable circular substrate having a radius (R1) comprising an in-use first visible circular scale displayed on the first substrate, the visible display comprising a plurality of indicia for indicating corresponding musical notes such that the musical notes indicated in the visible display scale ascend in frequency in a clock-wise or anti-clockwise direction; a second circular substrate having a radius (R3), the second substrate being arranged to be substantially concentric and rotatable relative to the first substrate by the fastening arrangement to enable the second substrate to rotate relative to the first substrates, the second substrate comprising a polygon with vertices of the polygon being located along the circumference of the second substrate, the second substrate comprising respective indicia corresponding to each of the vertices for indicating a respective musical mode selected from a set of a plurality of musical modes.

Device and method for teaching/learning music including a board having horizontal lines with spaces therebetween, representing a musical staff. The device includes first insertion slots arranged in the musical staff. The first insertion slots match keys of a keyboard musical instrument. The device includes second insertion slots arranged in parallel to the first insertion slots. Each of the second insertion slots indicates an accidental sign with adjacent first insertion slots. The device includes first pegs configured to insert in the first insertion slots. The device includes second pegs configured to insert in second insertion slots to indicate an accidental sign. The device includes interchangeably clefs individually placed when needed adjacent to the musical staff. The first pegs insert in the first insertion slots, and the second pegs insert in the second insertion slots such that their position indicates a musical tone corresponding to pitch produced by the keyboard musical instrument.

A simulated musical string instrument formed of plural shaped sheets of rigid material, such as cardboard. There is a top sheet forming a top surface of the simulated string instrument body, and a bottom sheet forming a bottom surface, and multiple sheets between. A simulated fingerboard is attached to the top surface. The top sheet and fingerboard gets stickers that show parts of the simulated string instrument body including openings and notes. There is also a simulated bow guide and a simulated bow.
