It's composed by Akira Hashimoto too... There is no space to write more. By the way, The short-rolling-city-music tunes first~forth are composed by my original tuning system. If the used instruments are the pianos, D scale and A scale are 55.55 cents and other scales are 0.00 cents. The classical guitar arrangement is just to play the top string and that tuning is 55.55 cents. This tune is composed by another scale system. If 55.55 cents scale is represented by "a", the scale system is {Ab, Ba, Cb}. The first tuning system I've written here is named "Akiran". The second one is named "Alan".
