Hi! Just assessing Henry here, I guess. @Henry Ng Tsz Kiu note that accordionists overall, specially those who are amateur, or just interested in performing, will know as much as any non-player (but musician) of the ways this instrument may be properly engraved. More often than not, as it happens with many other instruments, we "convert" the information to our format on the go. I fear something similar would happen to the piece you've brought to my attention. Now, in regards of the accordion scoring of this PDF I'd say that : RH specified at the beginning of the piece do not match with the provided sounds (LH could, but I'm not certain, it sounds like a Soft Bass and it definitely has no soprano voice sounding in those very first bars that I'm discussing right after this bullet) MMM or MM for the RH are the ones you're looking for, at least judging by the soundfont which appears to be a french musette, so it's either that or open violin register. Note that no registers work for providing thirds neither accordionist spawn them on the go. I'm seeing the working score and I just don't get why there are so many notes that are just not present. Note that not all accordions have these, some 3-voice Piginis and other famous italian concerto accordion brands prefer the dry sound of the harmonium register, LMH. or 4' + 8' + 16'. Your sound is 8'+8' or 8'+8'+8', assuming it's the one you are seeking for. Chord movements by semitones are to be avoided if possible. Otherwise, you'll be inflicting tremendous pain to the accordionist, assuming Stradella system since it's the one you're using. So, without extending myself much, let's just review some examples. These are M15 to M18 if I'm not mistaken. RH register, according to the audio, should be MMM or MM as I mentioned. Bass voice doesn't sound like Soft Tenor but that's minor. What's not minor is that F#dim and Bdim are so far away from each other and from the G7 and C buttons, demanding unneeded agility. Here there's no other option than to briefly discuss voicing. The voicing on standard 6-row stradella accordions with 2 rows of basses and 4 rows of chords is root+m3+7dim (and depending on the register, that can be doubled or tripled in octaves above and below). There's no fifth sound, neither in the 7 button chord, allowing the accordionist to essentially do a Xm6 or a Xº by using the dim button and the proper bass, and some other interesting combinations. And thus, all these red notes are... Not quite accurate, to say the least. According to the register you are using in the score (soft tenor), chords should be an octave higher with the proper voicings. No chord button alone produces more than 3 notes. M/m -> 1-M/m3-5, and for the other two (7, d), you take the 5th. You can find more information about Stradella voicings here in case you be interested in making it right. I have briefly talked about this for a reason, since you're not doing the complete Xº tetrad, the symmetry of chords marked "d" is in principle broken. But since I don't think it's gonna be a problem because the F# is already being played by another instrument, in that excerpt I would change F#º by Cº, which is very close to the G an C chords you're gonna play afterwards, and also, on a similar fashion and by using a similar argument, I would change Bº → Fº. Note that similar occurences happen throghout the whole piece. Finally, there are many register changes that are not reflected in the audio at all. In fact, since the very beginning it's clear that there's no "Clarinet M" sounding, but a French musette. While I can understand the limitations because most usual accordion soundfonts come with musette or in two voices already, there are plenty of incorrect examples. Here I tried to point out some. M26-28. The "Master" register uses 5 voices in the bass buttons, 5 because the contralto doubles the alto voice in half of the octave and the tenor voice in the other half, adding to the previous Soprano (2') + Alto (4') + Tenor (8') + Basso (16'). The website I shared notes C to F in alto and F# to B in tenor, but truth be told, this depends 100% on the manufacturer. On the right hand we got a fair deal of strange stuff too. You write "Musette Imitation", which consists on 2 middle voices (8'+8', one lightly detuned forward, usually) and a voice that's an octave higher. And that's for all notes, not jut for the ones you'd like to double, sorry. What's usually the benefit of changing registers that much in a piece? Little, unless you are Gianfelice Fugazza and you know exactly, and I mean exactly what you're doing, in the context of a pedagogic piece, an étude, an example, or a concerto piece. So I can assure you that with no loss of sound quality or musicality, had you removed all RH register changes and replaced them by an open violin (8'+8') and/or a musette (8'+8'+8') register, the sound would be closer to what the audio depicts and probably to what you were seeking for, since: Accordion, yes! Any accordion? Nein! A French musette accordion, a Cavagnolo, a Mengascini. Not a dry Pigini and if you wanna be just right about the french sound, not even a Hohner would do the trick. Ah, and these are often traditionally button accordions, not keyboard accordions, but you'll find a handful of them too. By doing what I suggested, you'll get rid of difficult/uncomfortable sections. Apart from the chord issues, we'd clean up things like these: Not impossible at all. But if you don't have one of these expensive accordions (that won't sound like French musette) that come with chin switches, you'd better pray these three registers are close enough. And just in case, the other hand is busy handling the bellows. And again, your working score (which I assume you used for the audio) doesn't correctly notate the passage according to the registers of choice. That said, the piece was nice to listen to. Not my turn to evaluate it, and I don't really want to bore you further, but the "Engraving" and "Playability" parts (which are definitely related in my opinion... Something may be possible to perform but its actual playability could be demeaned by its poor engraving) would not get a pass from me, sorry Wieland. I mean: your score frontpage looks very nice, it's original, and imo shows great care for it (though, why does it say 15 of 24 if this is the XXI? Or I'm in the wrong?). So, what happened here? Why none of that permeated into the score itself? Lack of time? Perhaps indolence? Lack of inertia or eagerness cause many may not make use of it for judging? I'm sorry if I'm being hard, but I'm not ill intentioned at all here, I just do not understand. I may not agree with every engraving choice you made in your XXI Praeludium for piano solo but that shows how you could have got a way cleaner score out of this. Or maybe not? If you don't mind, Weiland: what software are you using? Musescore 4? I think this reply is long enough already. I wish you the best for this competition. May you find any of this of help. Best regards, Daniel–Ø.
