Method and device for facilitating learning of musical scales on string instruments

A method for facilitating learning of musical scales on string instruments, comprising:

• providing a visual scheme printed on a substrate consisting of blocks to be positioned just below notes of a scale when fixed on an instrument, each block being formed by the overlap of two rectangles in distinct sizes and color patterns, which serve as space for accommodation of different didactic information including a cipher of a note and quality or degree of the note;
• providing a manual containing information for the understanding and proper use of the visual scheme;
• and
• providing a musical background containing tracks that sound in the same frequency or tonality of the visual scheme.

A method of installing adhesive labels printed thereon a visual scheme onto an instrument, comprising:

• printing the visual scheme on adhesive labels in the form of a foldable carton;
• folding the foldable carton;
• separating from the folded carton a unit suitable to be installed to a space between two metal filaments on the instrument, but in folded size;
• introducing the unit into the space underneath strings while adhesive still attached to an adhesive substrate;
• rotating sides to detach the adhesive substrate;
• repositioning and aligning the unit of adhesive labels underneath the strings;
• and
• attaching the adhesive labels on instrument arm in the space.
