Viola (or ‘alto’) fingerboard charts showing the locations of all possible musical notes between the first and third positions. One chart uses the Solfège-based naming system (Do, Re, Mi, …), while the other uses the alphabetical system (A, B, C, …). The charts correlate each note with its position on the musical staff, using color-coding for each string. They also include suggestions for tape placement for those who use that method. These charts are based on an equal-tempered tuning system.
