This is a Homage To Mompou, a leading Catalan composer in the 20th century, known for his "discrete" music, a Spanish Satie of sorts (in case you don't know him).
Ivor Mairants was the leading jazz and dance-band guitarist in the UK for a few decades, and of course author of many guitar books of varying quality.
So, a jazz musician giving a homage to a classical composer. The intro is quite bluesy, but in a non-obvious way. At one point the music speeds up a little, then a Spanish dance enters, the "Jota" before the outro. Lots of jazz chords along the way, yet without sounding jazzy.
I received this score yesterday, worked on it yesterday evening and late this afternoon. It's an extraordinary piece, which I'lll return to at some point. I just wanted to give my first reading of it, and admit there are one or two small errors in the performance. I learned from some Ivor Mairants books when I was a teenager, so it's good to see a mature composition from him. I believe this might be the first recording of it.
