So, today I went over to Peter's house, and we worked on the plainchant. It's easy to underestimate how much effort goes into a recording. I had originally thought we might be able to do 2 pieces, but it became clear early on that we had quite enough to do with just this one. It took some time to set up the effects processing and get that fine-tuned; as for the music itself, we worked on phrasing, tempo, dynamics, tonal quality, and pronunciation. It amazes me how much control is required. It's one thing to know what you want the music to sound like, and it's another thing entirely to be able to make your voice do that exact thing each and every time. There was some software to fuss with, and then the process of actually capturing the performance, but it all turned out pretty well, and you can listen to the result here. Afterwards, we enjoyed a nice dinner at a Mexican restaurant.
