explaining...
let's list the possibilities in the field:
1) I play Vattelappescolo (a Baroque composer who has kindly made himself available for simulation) on an instrument from an era different from that in which Vattelappescolo lived;
2) I play Vattelappescolo on an instrument from the era in which he lived and from the area where he operated;
3) I play Vattelappescolo on an instrument from the era in which he lived and from an area where he did NOT operate.
Tall three possibilities are legitimate.
1) See Gould and Bach, and not only them, many ancient and modern repertoires have a tradition of transcriptions, and few compositions were written thinking specifically of one instrument. Or rather, even if the compositions had a close relationship with their own instrument, it was widespread practice to perform them in transcription or, for the same composer, to prepare different versions. These practices are more present in certain eras, but since we follow "TODAY'S" practice, then conceptually it would be enough to say that today it is possible to perform Vattelappescolo on a Hammond organ without anyone dying.
2) the more obvious version. Vattelappescolo with the sounds of his era.
3) more than legitimate version, Vattelappescolo played by an unknown contemporary Finn who, during his travels, transcribed a performance heard in Busto Arsizio. In reality, it could be an interesting starting point, which I believe is consistent with today's historiographical trends.
Option no. 4 is missing ...
4) I play Vattelappescolo on the modern instrument corresponding to the instrument for which the piece was written.
What that means is that I play our composer's piece on a modernly constructed harpsichord, which can be a standard or double harpsichord, perhaps depending on the environment where I play, respecting the original idea without distorting the way the piece sounds and using a modernly constructed instrument that will surely be better than an era instrument.
Perhaps I see things from another point of view, but thinking about how the composer conceives the piece, I would not feel comfortable using different instruments.
It would be like in an orchestra using, for example, viola and clarinet instead of violin and clarinet ... it would sound different, even if it wouldn't be quite that serious since it is still two strings ... or, as often happens today, the tenor trombone instead of the alto, which would be even less serious since they are two instruments of the same family.
A different case would be one that happened to me in one of our past workshops, precisely in the one for the Christmas Mass.
Among the people who had seen the scores, the possibility of performing my Gloria with the organ instead of the piano was suggested to me, since it is always a keyboard instrument (so the person said).
I responded categorically no ... I would not have been able to listen to that piece on the organ because it would have "sounded" too different from my original idea.
So by extension, not being able to ask Vattelappescolo, I would try to perform the piece on an instrument as close as possible to the original one.
The only exception to this "pseudo-rule" (entirely mine, of course) is the case in which the composer himself made a transcription of the piece for other instruments ... let's just say that arbitrarily using an instrument very different from the original would seem to me a sort of imposition on the composer, and certainly piano and harpsichord are very different in sound, dynamics, touch, etc.
It is also good to remember that there is a substantial difference between clavichord/harpsichord technique and piano technique ... it is difficult for a great harpsichord performer to also be one on the piano and vice versa, simply due to a physical issue.
The case of Rossini's Petite Messe Solennelle is emblematic: Rossini himself made the transcription for orchestra (originally for 2 pianos and harmonium), knowing that sooner or later someone would do it and not being able to bear the idea that someone else would lay hands on it, perhaps obtaining results far from his original idea.
Tantamount to say, the original version of this mass is decidedly better than the one with the orchestra.
