For almost all of the music we sing there are on-line rehearsal aids.
To use these click on your part; you will hear the full set of parts with your own part emphasised. If the current music is available on-line you can access it by clicking the links in the section below; for Midis the relevant file will be downloaded to your device; for MP3s the file will be played on your device. If you want to download an MP3, once you have opened it, use a right click and choose 'Save Audio as' to save to your device file manager.

Chord Perfect Practice Aid
The Librarian can provide you with access to this aid on request. The MP3 files you download contain the sound of experts singing your part for you to follow.
Choralia Practice Aid
Choralia is an alternative resource to Chord Perfect which you can access here without recourse to downloads. The voicing is synthetic and you are recommended to subscribe to the service to remove the advertisements.
Once you have opened the site click on the MP3 box (top left). Scroll to the bottom of the H's to find Handel's Messiah (edition 2) and click on the loudspeaker icon in the same row.
On the resulting page the entire group of choruses for each part is shown in sequence, so A, T and B will have to scroll down
David's Mark ups
