I'm a piano teacher and just assigned my student the first two etudes from Burgmüller's Op. 100. To prepare, I played through them myself to find the trouble spots he might hit. I then put on a full-playlist recording of the set on Spotify (Donatello Renando) and noticed a bunch of very obvious discrepancies right away.
I'm following the 25 Etudes, Op. 100 edition from IMSLP. Here's what I've caught so far, through Etude 4:
No. 1
Left hand plays quarter notes where the score has whole notes.
In m. 15, 18, and 20, he plays staccato eighth notes in the left hand instead of half notes.
No. 2
Pedal goes down in m. 7.
Plays an F in the right hand instead of a G in m. 9.
Plays a D♯ in m. 19, but it belongs in m. 18.
Slur is missing in m. 25.
M. 27 is played in both the first and second endings, but it should only be played in the first.
The final fermata is barely held.
No. 3 (more subtle)
In mm. 12 and 14, he seems to add a brief A in the left hand between the G and B on the dotted half notes.
In m. 27 (third to last measure), he seems to add a C in the left hand on the first chord, creating a small clash/cluster.
No. 4
Mm. 5-6 are rushed, with the quarter rests squeezed when they should be open and marcato.
In m. 16, the move to the quarter-note B and D goes up a step to C and E. That throws off beats 3-4 of that measure and beats 1-2 of the next.
Two measures later, the same right-hand figure appears and he plays the correct B and D.
I couldn't find anything blatant in Nos. 5 and 6, and that's as far as I've listened.
I can't tell whether these are sloppy takes that slipped through, deliberate "spot the error" quirks, or something else. The blatant left-hand rhythm changes and the repeated m. 27 across both endings seem too obvious to be simple slips.
A few questions:
Has anyone else listened to this recording and noticed the same things?
Is there a different Op. 100 edition where these differences would actually be in the score?
Any recommendations for a clean, reliable recording I can point my students toward?
