Unnecessary accidental

Post by TimAllenMusic » Fri Aug 11, 2017 1:40 pm

I've entered a passage of music that has some interesting modulations, which result in one bar having an Fb chord throughout. In the bass-line, the repeated Fb has a repeated accidental on the 6th quaver (8th-note), which I don't believe is necessary. Any suggestions on a) why it's appearing, and b) the best way to remove it?

(Not shown in the screenshot below - I have a key signature of four flats).

I've encountered something like this but very rarely; if you enter a note that has already been altered but add the same alteration to it, Dorico adds it because it thinks you want a "reminder" or simply want to see the alteration there again (for whatever reason). You can clear it by typing the alteration keys [0,dash,equals] or using ALT+[up/down].

Out of curiosity, did you enter the music with a MIDI keyboard, computer keyboard, or was it pasted (at once or in chunks)?

In the properties panel I believe there is a way to hide accidentals.

So this makes me think 2 things.... This seems like piano part, if so.... Dorico will show the cautionary accidental if F natural was used anywhere in the measure, which leads me to wonder if the F on beat in the right hand is an F natural by accident hiding the accidental?

I would check the properties panel for every F in the bar, and see if it one is accidentally hidden.

Ooh- this has got more interesting. First of all, thanks for the tip about the properties panel - I've checked all the Fs and none of them have their accidentals hidden. Hiding the accidental on the troublesome Fb, 6th quaver of the left-hand part, solves the issue (in that it now looks correct).

I'm still interested in why the Fb on the 6th quaver was created in the first place. I used thiagoriberio's suggestion above of selected the errant note and using ALT+down then ALT+up to see if this fixed it, and it didn't - ALT+down moves the note to an Eb (no accidental displayed due to the key signature), and ALT+up takes it back to the Fb, with the accidental showing. More than that, it exposes another unnecessary accidental - moving the Fb down to an Eb takes away the accidental on the Bb in the right-hand part at the same rhythmic position, which I hadn't properly noticed before. This is another unnecessary accidental - the B is already flattened in the key signature, and hasn't been amended earlier in the bar. In fact, there's already been a Bb in the right-hand part, one-and-a-quarter beats into the bar, and this Bb hasn't been given an accidental, whereas the one above my erroneously accidentalled Fb in the left-hand has been given one. Quite odd! I guess I can hide this one too, but I'd be interested to know why they were added in the first place?

Tim: can you zip up and share this project or flow with us? I'll be glad to investigate for you.

Feel free to PM me directly with it, if you wish.

These accidentals are shown when you choose Show cautionary accidental in Notation options > Accidentals > Cautionary (courtesy) accidentals > Notes with augmented or diminished intervals because, well, Fb--Bb is an augmented fourth. I guess they're not shown when the Bb appears earlier because Bb and Fb are not played at the sime time there.
