hasBara is an ensemble work for any instrument (or voices). The open score calls for improvisation, and directs the musicians to alternate between solo and group playing. The work was commissioned by Musica Nova consort (see earlier version), and later performed by Mutu ensemble (video below).
The musicians oscillate between free improvisation and notation: the latter slowly transforms into free material, opening up to exogenous influences by gradually de-composing the pre-composed material. Later on, the opposite process takes place while the musicians “abandon” their freedom and gradually return to playing prescribed material, surrendering to the material’s “demand” for stability. Thus, hasBara interlinks improvisation and notation by gradually melting down notation or by directing free improvisation onto a notated path.
