This edition includes three versions of the same piece for the talented, beginner, intermediate and advanced bassist.

Trochu Rondo was composed for Posta100, an international project to celebrate the centenary of the birth of the Czech double bass virtuoso Frantisek Posta (1919-1991). Directed and devised by David Heyes, Posta100 will include 100 one-minute pieces for unaccompanied double bass by leading composers writing for the double bass today.

Eric Funk writes: "Here you go, something I hope you will find to be “fun”. It’s a little 1 minute, 23 second Czech-style dance in rondo form (troche rondo means “little rondo” in Czech).

I’m thinking back and forth between arco and pizzicato. I’ll leave it to you and our collaborative approach to determine what is best for double bass, since I obviously don’t play the instrument. You might find sections that speak better an octave up, you might have many ideas that lift this into something even more special. I trust you completely and agree to any edits you might feel best reveal this happy piece, like something you might hear a folk player performing alone in the Bohemian Forest. Jaroslav Krcek, Musica Bohemica, is Tomas Svoboda’s best friend. I’ve heard so many recordings by that phenomenal group. I let memories of that inspire this piece."

Trochu Rondo was premiered by David Heyes (double bass) on 1 April 2017 at West Harptree Church (West Harptree, Somerset, UK).
