There are several different versions of the hymn "Ein' feste Burg ist unser Gott" by Martin Luther including one arranged by J.S. Bach. This music has been composed using the materials taken from those. Beginning with a chorale by French Horns and Euphoniums, the theme is introduced from lower to higher registers and it enters into the part of combination of thick chords and fanfare of major triads. After a rhythmic divertimento with fragments, the theme appears again in tutti. After the recollection of the first part, the music ends with combined two chords, Bb major and F# major triads. It is an ode to Reverend Martin Luther and his achievement as well as a paean to the brass instruments and their ensemble. This piece has premiered in the “Concert in Commemoration of the 500th Anniversary of the Reformation”, by the brass ensemble of students of the Seminar by Professor Kiyonori Sokabe of Senzoku Gakuen College of Music, Yasuko Ii (organ) and Prof. Sokabe (conductor) on October 13, 2017, in the Reinanzaka Church, Akasaka, Tokyo, Japan.

The composition consists of two parts. 1. Andante, 3/4, d minor, 2-voice fughetta. The tonality flows one to another but music as a whole will rise towards the dominant of d moll. After a perfect cadence, it enters the second part. 2. Agitato 3/4 d minor scherzo. After pausing once on B flat, there come cadenzas in the order of trombone and trumpet. Recalling the theme of the fughetta, the coda reaches the end keeping the tempo. This piece has been premiered by Kiyonori Sokabe(trp.) and Norikazu Naoi(trb.) on July 22, 2017, in Tokyo.

A harp has 7 pedals, which correspond to 7 notes, i.e. do-re-mi-fa-sol-la-si. Each pedal can take three different positions, namely flat, natural and sharp. Therefore, a harp can be set for 2,187 different modes (scales) (3 to the power of 7). The instrument could be considered as a "function". The 7 notes can be mapped to 2,187 different scales. The name of the composition "M=h(n)" is derived from the mechanism. In this composition, the 22 different scales are used . This piece has been premiered by Makiko Suzuki in "La Folia-a concert for openly-invited compositions" on July 21, 2017, in Tokyo, Japan. The composer thanks to her for her invaluable advice on the music

The title of the tune is a HAIKU by Hakusen Watanabe(1913-1969). This is a terribly scary poem to EVEN me, who has been born more than 10 years after the end of WW II. The war must be casually standing in the end of a corridor. The instrument, TRUMPET is inevitably linked to the military forces. I wish a trumpet to express the horribleness of the HAIKU, implying wherever the war is hiding and waiting. The tune includes several quotes from the music relating to and written during the war by Schoenberg, Prokofiev, and Shostakovich. This music has premiered by Mr. Kiyonori Sokabe in the concert "Composers in Chugoku/Shikoku in Tokushima 2016". The revised version has been performed by Mr. Sokabe on December 22, 2019.
