Sibelius is one of the featured composers in a new range of musical-themed chocolate available internationally from today, 1 April 2025, and designed to attract a whole new generation of consumers to classical music.

Building on the concept established by Austria’s famous Mozart-Kugel from 1890, Chocol-o-tunes takes the notion of musical confectionery to a new level for for the 21st century. Embedded in the chocolate bars are microchips attached to miniature loudspeakers (about the size of a hazlenut in traditional chocolate bars). When the chocolate is eaten and these microchips come into contact with gastric acid, a piece of music is played, apparently emerging direct from the body of the consumer. A company representative has praised the sound quality thus obtained, describing it as ‘tummy-wobbling’.

Musical works featured in the initial release of Chocol-o-tunes include:
— Sibelius: Symphony No. 4 (slow movement)
— Mozart: Ein musikalischer Spaß, K 522
— Haydn: String Quartet in E flat major, Op. 33 No. 2, ‘The Joke’
— John Cage: 4’33”

Chocol-o-tunes is available from participating retail outlets and costs € 15.00 for a 100g bar.
