On Tuesday night, Rhys pointed out that the choir members would benefit from some self-training on the Gounod St Cecilia Mass. Here are a few links that might help.
The site that Rhys suggested was CyberBass. The CyberBass page for the Saint Cecilia Mass is here and in principle you can play the different parts of the 6 choral movements with the player embedded in that page. I say “in principle” because you may or not find the embedded player works for you. For me, on Windows, it works with Internet Explorer but not with Mozilla Firefox, which can’t find the necessary plug-in. It’s supposed to work on Macs too.
Alternatively, you can download MIDI files and play them on your computer. CyberBass used to allow this, but no longer does. I’ve searched for MIDI files elsewhere and found them at the Choral Public Domain Library (CPDL) and Silvis Woodshed. I found the Silvis MIDI files preferable, because each track is named after the vocal part it represents, whereas in the CPDL MIDI files the tracks have names like “Staff” and “Staff-2”. The Silvis MIDI files for the St Cecilia Mass can be downloaded as a ZIP archive. Each file corresponds to one movement and contains all the parts together and so is best played with a MIDI player thet lets you emphasise the one you’re trying to follow. In the past my preferred MIDI player has been the Van Basco Karaoke Player, however I haven’t managed to install this on Windows 7, so I’m looking for an alternative. At the moment I am using MidiPlay, which is pretty clunky but does the job.
