From the Guidelines:
Ward choirs and other special choirs can teach and inspire Church members.
Here are some examples of ways this can be met:
You can fulfill that role in a variety of ways. You don't need 20 singers, 4 each on the SATB parts. If you have only one or two willing singers, you can fulfill the purpose of a ward choir. Really. Simply have those two sing once or twice a month (the suggested frequency for ward choirs). You don't need special arrangements. Underscore the role of this "choir" by having them first sing from the hymnal always (though that is certainly not an imposed constraint, according to the Guidelines).
I know a ward in my stake that has a handful of really talented singers, but they are not organized into a ward choir. They believe that they don't have anyone capable of leading the group, so they do nothing. What a loss to that ward! Instead of a "choir director," the bishopric could call a "choir coordinator". The singers can gather, practice, and stand and sing without the traditional leader. That's made even easier if they have a really competent pianist who can set and hold tempo for them, etc. Are you missing a Bass voice? Then omit it! The piano will carry it.
Can't find any consistently willing singers to form a "duet choir"? Then use a "hymnal choir" once a month. Designate a well-known, well-loved hymn as the chosen piece. When it's time for the "choir" to sing, invite anyone interested in singing to come up from the congregation. Then sing the hymn. After you do this a few times, you can even indicated that the women will sing one verse alone. Simply say it into the microphone as they come up to the stand (rostrum). Even if you have a successful choir, this can add variety and allow more people to participate in music. It does help if you have a least a handful of singers who will sing, just in case no one else comes up. If your congregation is particularly resistant, you can have they hymn practiced in Relief Society and Priesthood meetings for a week or two beforehand, and encourage them to join you when it's time.
Don't have any singers? (I don't believe you, but for the sake of argument....) Then have the ward pianist/organist play a solo hymn once a month. Or have the primary sing once a month. The primary children are always willing to sing!
Expand your vision further by using the "special choirs" idea from the Guidelines. Schedule the Priesthood, Relief Society, Young Women or combined Youth, and Primary organizations to sing regularly. It really can be a simple hymn. It is enough to meet the goal and accomplish the purpose.
There really is something that you can do. There is a lot that can be done to meet the goal of ward choirs and worship music without having the traditional SATB choir.
