Blue Mosaics is a contemporary solo work utilizing fragmented musical ideas to build a cohesive soundscape. It is distinguished by its interplay between light, rapid textures and sustained sonorities.
The main difficulty lies in executing the rapid shifts in registration while maintaining an even, mosaic-like texture.
Comparable difficulty and character — good candidates for what to learn next.
Blue Mosaics is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Blue Mosaics lasts about 4 minutes.
Blue Mosaics is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
