Openscore: Rules for playback of trills with accidentals

• Feb 18, 2018 - 11:52

Is it allowed to insert an invisible and silent note in voice 2 for the correct playback of trills with accidentals?

And could someone clarify me about the right corresponding pitches in the attached example, especially concerning the trill with flat above the C# in D-major, shouldn't it be same pitch as a trill without the flat?

(For the other I think it's clear for me: For the note D with a trill flat the corresponding pitch is Eb and for the natural E again, isn't it?)



Yes, you may do this. I think I've said "no" to this before, but having been shown a case where playback sounded particularly awful, I've been persuaded to reverse my decision and allow invisible notes in situations like this.

You should make the extra note silent and invisible, but you should keep the accidental visible and move it to where the trill is. You can make the accidental small via the Inspector. If the accidental affects any notes later in the bar you may have to add an invisible natural.


Hopefully someone will implement a proper fix soon to allow accidentals to be added to ornaments.

In the above image I made the natural sign invisible because I thought it unnecessary because accidentals on ornaments are not supposed to modify notes later in the bar. However, the point is a bit ambiguous, and I have since read a notation style guide that recommends using courtesy accidentals to make it clear what is intended. This applies to notes later in the bar, and it also applies to other ornaments later in the bar.

Thanks for this, and I know I'm a year late, but how would I do a turn? And, I can not place anything above the symbol, in this case, the turn. I need it to go up and down chromatically with a flat above and a natural below. Again, thanks for posting this.

Regarding the trill with flat above the C# in D-major (1st bar in your picture), I think the engraver has lost count of ledger lines and the note is actually supposed to be a D trilling to an Eb, like those in later bars but an octave above. You should check this in other editions if any are available.

Thanks, I will do so (concerning your first comment).

After cross referencing: In a second edition for full orchestra, which uploaded on Imslp (there are only these one - as mentioned in another thread, the "urtext" isn't available) it's notated in same way:


But I've found on Imslp a transcription for violin and piano:


So I suppose it's a trill over cis and the flat is more for clarification.

Btw. concerning my guess and a little bit despites this topic: in the original score are a lot of accidentals for clarification (I don't know the right expression in English), for example at the beginning of a measure is a sharp before a C (key signature D major), when in the measure before there was an natural. It's necessary to transcribe all these accidentals?
