The full ringing of Aachen Cathedral, recorded on Christmas Eve at midnight.
Nice to see in the spectrogram how some tones develop only after the beat. And not always the loudest ones are also the perceived ones.

Mary’s Bell: strike tone g°+8, 2075 mm diameter and 5,800 kg.
Charlemagne Bell: strike tone h°+7, 1628 mm diameter and 2700 kg.
Joh. evangelist: strike tone d’+8, 1367 mm diameter and 1650 kg.
Joh. Baptist: strike tone e’+7, 1367 mm diameter and 1150 kg.
Leopardus bell: strike tone fis’+3, 1078 mm diameter and 800 kg.
Stephanus bell: strike tone g’+8, 1027 mm diameter and 700 kg.
Petrus bell: strike tone a’+1, 894 mm diameter and 450 kg.
Simeon’s bell: strike tone h’+8, 793 mm diameter and 300 kg.

The Mary’s Bell was melted down by the Nazis and re-cast in 1958. The bell motif is formed by the Latin hymn Veni Creator Spiritus.

After many years, I finally succeeded in 2017 to get a largely trouble-free recording. I recorded it from Katschhof, the place between the cathedral and the town hall and this time recorded it with wind-protected hypercardioid microphones on a high stand behind two lonely Christmas market stalls, and one hour before I visited all the security people (who guard the empty Christmas market stalls), discussed the recording and – important! – I showed them a place from where they could watch me without disturbing the recording too much.

For years there were always disturbances, unfortunately also with the acoustically most beautiful 3D recordings with OKM original head microphones 2014. Sometimes it stormed, sometimes it rained, sometimes the police drove over the Katschhof, sometimes a blower blew into a plastic print, or security people asked questions, or someone poked loudly with high heels into the Christmas mass. In 2017, hypercardioid microphones with windscreens largely blanked out the sounds of space and the wind.

I moved away from Aachen in 2018 and am happy to have this recording in my box. It gives feelings of home. For me, the cathedral is the most impressive thing in Aachen.
