The Brook Sings loud was commissioned by the Aberdeen Chamber Music Club for the Kungsbacka Trio. As this was one of the first pieces that the Club have commissioned, I thought it would be appropriate for the piece to have some sort of Scottish theme or influence. I have always been interested in Pibroch, classical bagpipe music that was prevalent from the 16th to the 18th centuries in the Scottish Highlands. I have not attempted to imitate the sound of the bagpipes; however, I have been influenced by some of the techniques associated with this music. For instance, the form of Pibroch can be loosely classified as a theme with variations. The unison melody at the opening of the work is restated noticeably at the climax and at the end of the piece, and recurs with subtle variation throughout. The structure of the melody also has close connections with Pibroch. The notion of taking a simple melody and adding to or embellishing it is central to the piece, as is a lack of strict metre. Although there is an absence of a strict beat or tempo, the music does at times have a strong rhythmic impetus.
The piece is in one movement and is punctuated by solo passages for each member of the group. The violin solo leads way to a fast, energetic section. The piano interlude juxtaposes the fiery faster music with calm music, and the cello cadenza paves the way to a slow, melancholy final section where the two string instruments are set against differing material in the piano.
