Class 15 includes mainly musical instruments (including electrical and electronic musical instruments) and their parts and accessories, as well as certain goods that create music but are not played by a musician, for example, musical boxes and robotic drums. However, goods that affect sound produced from another source, like music amplifiers or loudspeakers, and apparatus that reproduce music, such as compact disc players, are in Cl. 9.
Whilst pedals for musical instruments belong to Class 15 as they are part of the musical instrument itself, wah-wah pedals and other electric and electronic effects units for musical instruments belong to Cl. 9.
Class 15 also includes goods that are closely related to the production of music, such as music stands and stands for musical instruments, tuning forks, conductors' batons and colophony (rosin) for stringed musical instruments. It is worth noting however that printed sheet music belongs to Cl. 16 and downloadable electronic sheet music is in Cl. 9.
