triplets encoded as tremolo #426

Open jacekiwaszko1 opened 4 years ago

jacekiwaszko1 commented 4 years ago

In the example below dotted quarters with tremolo abbreviations should probably be interpreted as triplets:

tremolo-triplets1

In encoding each dotted tremolo quarter note should be encoded as triplet I guess:

**kern  **kern
*clefF4 *clefG2
*k[b-e-a-]  *k[b-e-a-]
*M3/4   *M3/4
=-  =-
*tremolo    *
4G 4GG  4g 4d 4B
*Xtuplet    *
12E- 12EE-L 4r
12E- 12EE-  .
12E- 12EE-J .
12E- 12EE-L 4r
12E- 12EE-  .
12E- 12EE-J .
=   =
12E- 12EE-L 4r
12E- 12EE-  .
12E- 12EE-J .
12E- 12EE-L 4b- 4g
12E- 12EE-  .
12E- 12EE-J .
8E- 8EE-L   4b- 4g
8E- 8EE-J   .
=   =
*-  *-

The problem is there's no way to render dotted quarter in Verovio:

tremolo-triplets2

Current MEI conversion:

I've tried !LO:N:vis=4., but it doesn't work...

I guess a good solution would be to add @dots="1" and @dots.ges="0" in MEI encoding to each tremolo note in this case:

tremolo-triplets3

The question is how to encode that in Humdrum - I don't think this is the most common style of notating tremolo triplets - I saw three tremolo dots above the note and I think there would be more examples of this encoding, so making it a default behavior might not be the best idea.

(BTW, tremolo dots mentioned here: #285(comment))

I can think of one possible encoding, mentioned in #306 - a visual change of tremolo note. Maybe !LO:N:TREM:vis=4. would be a good solution after all? What do you think?

That would be good, but I think even better is to have triplet eighth-note tremolos add a dot automatically in such cases, so I will work on that.

See pull request https://github.com/rism-ch/verovio/pull/1712 for triplet tremolos (which is related to this issue, although no tuplet numbers are included in this example).
