[MEI-L] encoding orchestra cast with alternative instruments

Wed Feb 1 09:15:48 CET 2017

Hi everybody,

yes , as stated in my initial mail I’m trying to take account of the following situation.

3 Oboe players
- 1 and 2 also play Oboe d’amore that might be substituted by Oboe
- 3 also plays Cor d’anglais that may not be substituted

The idea is to state somehow, that Oboe and Oboe d’amore (1 and 2) and Oboe and Cor d’anglais (3) are in exclusive alteration, AND that in case there is no Oboe d’amore available, 1 and 2 might keep playing their Oboe for those sections.

In the following suggestion by Perry:

> 6.      <perfResList type="substitution">
> 7.        <perfRes codedval="wz" solo="false">Oboe d'amore</perfRes>
> 8.        <perfRes codedval="wb" solo="false">Oboe</perfRes>
> 9.      </perfResList>

I miss the indication, which instrument is the “regular” and which one the “alternative”. Axels idea of @substitutes is comes way closer to that:

>           <perfRes codedval="wb" solo="false" xml:id="ob1">Oboe</perfRes>
>           <perfRes codedval="wz" solo="false" substitutes="#ob1">Oboe d'amore</perfRes>

Nevertheless it can be misunderstood I think, as you could read it as verb (1) or as noun (2):
1) Oboe d’amore substitutes Oboe
2) Oboe d’amore has a potential substitute, namely Oboe

Of course that’s something that c an become clear from the documentation, but maybe omitting the ’s’ (@substitute) would make it clearer?

Or are you trying to take into account the possibility that a performer may play more than one instrument, one or more of which may be substituted? In that case I do see the need for something more specific. However, I would like to omit repeating any instrument declaration. An alternative way of making explicit which instrument may be substituted would be to invent another attribute to point to that instrument. Then perhaps you could even omit @type:
