[MEI-L] Instrument settings and tunings

[Axel Teich Geertinger]

Hi Richard

Oh yes, now I remember! I am sorry! I was actually there to see your presentation, but the question had not occurred to me at that point :-)

Could you post a few examples here on the list for illustration and further discussion? I see in your customisation that you can also have an <instrName> element inside <instrDesc>. Do you have an example showing your use of <instrName> along with other content in <instrDesc>?

What values do you give the @family attribute in <instrName>? Is there a danger of doubling or conflicting information given in @code on <instrVoice>?

Best wishes,
Axel

Dear Axel,

We did some work on the problem of encoding instrument configurations earlier this year. We actually came up with a customisation which is published on github:
<https://github.com/TransformingMusicology/mei-tmus>, specifically, <https://github.com/TransformingMusicology/mei-tmus/blob/master/schemata/instruments.odd>.

We took the approach of extending <instrVoice> to include <instrDesc> and <instrConfig> elements. The <instrDesc> allows a more structured description of an instrument, while <instrConfig> is intended for instrument-specific set up. In our specific case we then provided a further customisation for lute tablature which extended <instrConfig> to allow elements for describing the tunings of the courses.

Our intention was that this generic provision could be extended for exactly the kinds of things you describe: organ registrations, electronic instruments.

We didn't make any provision for your second requirement, however, that of changes of instrument configuration during the course of a piece.

We presented this at MEC 2015 but since then we haven't really revised it. I think it's still quite experimental and really could do with some more testing and criticism.

Best,
Richard
