An improved music fingering aid has at least one decal fittable overlying the fingerboard and attachable to the neck of a stringed instrument. The decal includes string identifier indicia, a graduated position indicia series, and a plurality of interval demarcations that employ distinct colors for visual distinction. The indicia do not pair particular notes with particular colors. Instead the improved music fingering aid associates music theory with muscle memory to ensure sounded notes are played in near perfect pitch and, when playing ensemble, in tempered pitch. Contemplation and improved association of music theory is thereby enabled.
