Colourstrings is a string teaching method developed by Géza Szilvay and his brother Csaba Szilvay. The Hungarian-born Szilvay brothers started teaching in Finland in 1971. The first generation of Colourstrings children were raised at the East Helsinki Music Institute, and the Helsinki Junior Strings (Helsinki Strings) were formed from the Institute’s Colourstrings pupils. The orchestra won major international acclaim and made a number of records and TV appearances. Miniddlers in Musicland TV program became incredibly successful and resulted in sold-out string instruments in Finland. This was the start for the Colourstrings boom, and the method has since then spread all over the world also due to extensive teacher training courses.
