In her work Shades for four guitars (2025–2026), Tiina Myllärinen explores the instrument's delicate and richly nuanced colours, at times employing extended techniques. Writing for four guitars makes it possible to examine these sounds in different forms: at times as fragmentary musical events produced by a single guitar, at others as a slowly evolving texture created collectively by all four instruments. Shades is structured so that the guitar's resonance and sonority grow from movement to movement.

The piece begins at the threshold between noise and pitch (Shades of Crystal), then moves through a passage centred on a single tone, resonating with a cavern-like echo (Shades of Waves). The third movement focuses on the full, rich sonority of four guitars, ultimately evoking the polyphonic sound of church bells ringing from different directions (Shades of Bells). In the fourth movement, sonority is approached with a sense of nostalgia: we recall the past, sensitised to the inevitable passage of life (Shades of Memories, Epilogue).

This product includes the full score and the separate parts for guitars I, II, III & IV.
