Pachelbel wrote two organ settings on the hymn 'Ach Herr, mich armen Sünder'. This is the long version. Wait for the beautiful Clairon 4' that I used for the cantus firmus. This hymn is also known as 'O Haupt voll Blut und Wunden' or 'Herzlich tut mich verlangen'.
This French classical organ isn't the first you would think of when playing Pachelbel's organ music. However, it works very well.
