A quirky ragtime originally written for guitar duo (also available on this site), now arranged for various instrumental quartets.
It is called “bifocal” because of the brief bitonal effect in various places.
The rhythm switches gently from 4/4 to 3 3 2 /8 from time to time (when it does I have grouped the notes in 3s and 2s to make it clear – make sure they are not misinterpreted as triplets!).
The sound sample is performed by London Strings at Angel Studios in Islington, London
