3. Browsing through the score. "Structurally, the work is in two parts, a Sonata and a Fantazia. The Sonata is nervous and energetic, constantly exploring the opening figure of two falling perfect 5ths. This figure pervades the entire work.” Photograph: Idor Ak/Flickr

4. Ivor McGregor, composer and musician. “The Fantazia is a result of my lifelong fascination with the Viol Fantazias of Henry Purcell, written in 1680. It's as if Purcell had arisen from the dead, examined my musical language with head-shaking disapprobation, then used it to fashion a commentary on my Sonata!” Photograph: Idor Ak/Flickr

5. City of Birmingham String Quartet and Ivor McGregor (composer). “The Quartet also contains a quote from 'Riverman' by the amazingly gifted and tragic figure Nick Drake, whose music I discovered while writing this piece and became of great significance to me.” Photograph: Idor Ak/Flickr
