There are many things I think about when selecting music for a group. I am in the process of selecting music for the Women's Chorus.
Right away, there are certain obstacles because I do not have all the information needed to make the best decision: number of students, skill level, etc. I have done some research. According to last year, there were about 30 ladies and it was a strong group. They sounded very nice at their May concert. But this does not mean it will be at the same place as last year.
So, understanding there may be changes is important, new knowledge added to change the framework of the group.
The first thing is to simply look at music- text, rhythm, ranges. Is there a theme to the concert? Do you want two soprano parts going back and forth on a high G? Do the altos constantly hang out around G or A3? Is it extremely polyphonic and will each part have to be completely comfortable in their independence? Is it a song that has a topic I want a group to sing about? Will they feel silly singing the words and never connect with the song?
If it passed the preliminary test, the next thing to do is to play through it- either the vocal parts, the accompaniment, or preferably both. Is it interesting? I look to progression, rhythm, word painting, etc. Does it capture attention or will the singers zone out because it sounds boring? Is it a song that is easy to teach other concepts through?
I normally put all the songs that pass this preliminary test in a different pile. I then will listen to each of these songs on YouTube or iTunes. Often times I'll play it again.
Then I need to make decisions that become more difficult: What mixture of songs do I want that will shape a program that the singers and the audience will want to invest in? Personally, I like to find one song that the singers will have immediate and somewhat easy success on so they start to have cohesion and pride as a group (normally either a schmultzy pretty piece or an excitingly rhythmic piece with easy harmony). Then I'll add in a mixture of difficulty and of different concepts- I'm likely to choose pieces that force my singers to listen to different things. For example: at least one piece that is vertical so their ear learns and practices how to adjust where they are in the chord and at least one piece in unison so that they learn the value of not just listening in how they are a part of a vertical chord but also how to be one voice. Also, depending on how well I know the group, I will likely choose at least one song that has a concept my singers really need improvement on.
During this step I often will eliminate more songs or I will put songs away for a different time/concert. And sometimes when I switch out one song, I need to look at the other songs to see if it would still make a cohesive program.
It's a very exciting process, especially when I discover some awesome new song or I learn that I can program a song I have always wanted to program.
By the way, my Women's Chorus has a facebook group page. Even if you cannot sing with us, I welcome you to join the group simply to show your support- or let me know if you'd like me to add you.
Keep singing!
