Heart-shaped romance is an indeterminate composition that can be played with any instrument. It is presented through a music staff that draws a heart. On it, a lyrical and expressive melody -which explores both the sweetest and most passionate feelings- dominates the composition thanks to a calm speed. At the end of it, a repetition under the words "Repeat Freely" invites us to restate the music theme playing all musical variations we deem necessary until we decide that the work must be completed. For polyphonic instruments there are harmonic indications so that the melody can be accompanied. The composition will be premiered online during the III International Competition for soloists and chamber groups "Ro 2016", the unique competition in the world for performing graphic scores and the first musical contest organized through facebook.
