We have musicians who generally play by ear but need a key prompt when songs are added during the service that were not pre-planned. To avoid breaking the flow of worship whilst musicians search around for the music or discuss the best key, we have simply added to the author line eg. 'Brian Doerksen [D]' which works perfectly OK. We've done this for every song in our database.
Does anyone else have a similar requirement for their musicians or is ours a one-off? If there is a wider requirement, perhaps our trusty software writers might add a box specifically for this purpose?
If we are unusual in this usage, then it's not a problem as we already have the keys entered against all of our 976 songs and hymns.
