Content:  The First Suite in E for Military Band, Op. 28, No. 1, by the British composer Gustav Holst is considered one of the cornerstone masterworks in the concert band repertoire.

The piece was later arranged for brass band by Sydney Herbert, and this arrangement has been used as a contest set test piece on numerous occasions, including for the British regional brass band championships in 1970, 1983 and 2019.

Frederick Fennell, in Time and the Winds, observes that Holst's scoring for the work is so well conceived and organised for the band medium, that he must have had some previous experiences with groups of this kind. Indeed, Holst was himself a formidable trombonist, having already performed several seasons with the Scottish Orchestra prior to the composition of the suite.

The full score always existed and it could have answered all the questions which were raised in my initial study and in the minds of other conductors whose pursuits of definite answers in this has been an equal frustration." Among the questions raised were those concerning the scoring discrepancies associated with the alto clarinet and baritone saxophone. In light of these realisations, a new, revised score was subsequently prepared by English composer Colin Matthews, with the assistance of Imogen Holst and Frederick Fennell. This new edition was published in 1984 by Boosey & Hawkes.
