Comparison: Jag tackar dig, min högste Gud

Several differences are noted:

Location Difference Comment
throughout note timings and durations1) There were many minor adjustments made in order to better reproduce the music. Usually this consisted of slightly lengthening individual notes, so that they often overlapped. In play, this produces a constant melody line without audible gaps. However if there were repeated notes, a gap was desired so that the notes would remain distinct, so the first was often shortened.
bass clef, throughout shifted octaves Because of the 20-note scale available on the Roller Organ, it was often necessary to shift low “bass” notes up an octave. At the same time, “tenor” notes were sometimes shifted down an octave, to preserve pleasing intervals.
1st note G omitted Since the G occurs in the treble, its omission in the bass is appropriate for the initial pickup, especially since the following note is also omitted.
1st (full), 7th, 8th measure E omitted The low E (corresponding to an E for a common Gem) was not available in the 20-note scale.
4th measure D added in the treble harmony (alto) A full chord was evidently desired on this long note.
12th measure A replaced with B Although this changes the harmony slightly, it sounds OK. Perhaps this corresponds to the similar change in measure 13.
13th measure B moved up an octave Although this changes the melody line, it does keep the B in the treble.
13th measure A replaced with B With the G already moved up an octave, an A would have produced discord. Although this changes the harmony slightly, it sounds OK.
14th measure F# replaced with A The low F# (corresponding to an F# for a common Gem) was not available in the 20-note scale.
19th measure D added in the treble harmony (alto) A full chord was evidently desired on this last note.
1) These small differences are not shown in the illustration.
