Hi @Rafael Avila ! First off, I don't know if it is customary to use a transposed score for serial works. Perhaps due to the dissonant textures and lack of key center it is preferrable to a transposed score? I personally prefer transposed scores because then you see exactly what the player sees and the logic of the enharmonics is different and customized. Btw, would you provide an mp3 of the piece as well? I've noticed from the score that some parts of it might even be perceived as tonal. Now to picking at the enharmonics. In measure 3 you have the flute playing this: Since you have a leap here of a major 7th I would spell the notes in this measure as C#, B#, A#, Fx. And since the part continues in the next measure to D# and B it makes more sense (to me) to continue using sharps here. You might think that since the harmony underneath that is basically D minor, that using your spellings would be more logical in that context. That could be true, and I wouldn't blame you for keeping it the way you have it now. But it also depends on how devoid of key the piece actually is. Is this just a short moment of quasi-tonality in the midst of atonal surroundings? Or do various key centers actually play a part in the piece and how it will be perceived by the listener? On a cursory glance at just the beginning of the score it doesn't seem particular dissonant or atonal and uses lots of consonances and octave doublings. Like I said, I am no 12-tone serial connoisseur but this seems like a no-no for a serial work. Basically - if the piece is tonal here and there, adhere to tonal voice-leading rules in those situations. But if the piece is more devoid of a tonal center then spell the pitches as logically as possible within each individual voice regardless of what the other voices are doing in a sense. That's how I would do it. Thanks for sharing and I'd be stoked to hear this piece!
