Constructed here is an integrated system for the practice of playing the guitar for novice guitar players. Novice guitarists for popular music often give up playing it because they cannot keep practicing for the difficulty of realizing finger positions. An algorithm YG for giving optimal chord-form sequence for given chords was proposed [Emura et al., AST, 104–107 (2006)]. Authors construct an integrated system for guitar practicing by implementing YG. The new system deals with thousands of MIDI files combined with names of chords for them. The proposed system shows chord sequences as the TAB score, with corresponding fingerings generated by YG as the chord diagram. By using the system, users are able to play excerpts using not the difficult but simple pattern of chord-form. The system interacts with the user playing the MIDI guitar by showing the performed notes with an accompanying playback for current excerpt. The user is expected to be supported on playing it under a performance evaluation, where errors of fingerings are simultaneously shown with accompanying playback stopping or slowing down. The performance of the system is confirmed as better than the usual style of practicing in terms of occurrence frequency of errors. [Work supported by HRC, Ryukoku University.]
