Aquarelle and The Orchestra is a response of artist to the Symphony Orchestra rehearsals and public performances. Artist’s role is to “document” process of music playing, focusing on interactivity with listener. Viewers/listeners of the rehearsals – groups of children and adults are to make an input in such “documentation”. “Documentation” process in aquarelle or/and ink is to be documented into video that is to be a part of visualization during orchestra’s annual performance “Fantastical Classical”, which is also recorded and combined into a streaming media on the artist’s and orchestra’s website.
