| 解説 | 関西学院大学応援団総部吹奏楽部の創立60周年と関西学院の創立125周年を記念して、2014年に委嘱された作品です。 この曲は、ゆっくりとした序奏から始まり、徐々にテンポを上げながら新しい主題を展開し、音楽が自らの勢いを生み出すような構成となっています。 終盤では、ラヴェルの『ラ・ヴァルス』の終結部が引用され、止められない勢いを象徴しています。 （出版社のオリジナル解説） The Unknown Journey was commissioned by Kwansei Gakuin University Symphony Band which was established in 1954 and has grown to become one of the top college bands in Japan. The composer chose the title as the piece seemed to create its own momentum as it developed， starting slowly and continuously increasing the tempo. Towards the end it gradually transmogrifies into the closing bars of Ravel’s La Valse， a piece which perfectly characterises the idea of unstoppable momentum. |
