Sport has an inner relation to sound and rhythm, which is different from activity to activity and from country to country. Danish ‘popular sport’, which started as a gymnastic movement, delivers a particular model of combining sportive activity with joint singing. People sing together both in local meetings and in the large national sports festivals as well as in the people’s academies of sport. This particular feature has its roots in nineteenth century’s social self-organisation. Democratic movements spread as singing movement, and this got new life by twentieth century’s rock music. Singing sport implies some challenges for education in Sport for all. In a time of globalisation, it is not any longer self-evident ‘what to sing’. Singing sports open towards new forms of intercultural communication and singing democracy.
