Music is cultivated in the music city of Leipzig not only in professional ensembles of international standing. Music is an art that lives and is practiced in the citizenry. The fact that the love of music in Leipzig has its basis in the city's homes has been brought to life and made publicly visible in a concentrated way during the previous Notenspur Nights of House Music 2015 to 2019. Right at the first time, an unprecedented dimension of civic music-making in a city was achieved: about 400 volunteer musicians, about 100 volunteer dedicated hosts, more than 1,500 visitors at 60 house music venues. The associated world record for the "largest number of simultaneous concerts in one city" (previously Ankara with 41 concerts) highlights the unique situation of Leipzig's musical life worldwide and has generated considerable media interest. At the 2nd edition in 2016, there were 62 house music venues, the participation of musicians and visitor interest was as great as at the premiere, in 2017 there were almost 70 house music evenings, in 2018 there were more than 80 - the interest among hosts and guests continued to grow. In 2019, together with the Beethoven Society, we very successfully organized the "Notenspur Festival of House Music" on a December weekend.
