Please find below some useful websites to facilitate your private rehearsing.
Audio files are provided, which allow singers to gradually learn their parts by listening to electronically-synthesized sound. The main technology is named Virtual Singer (VS), as lyrics are "sung" by electronically-synthesized human voices.
**** Testimonial **** This site is such a blessing to the serious choral singer who desires to learn a piece of music perfectly. My favorite things are the ability to slow down a movement and really get every note, then slowly bring it back to full speed, and the fact that the movements just continue to loop. i sometimes leave a difficult movement on in my home, and just let it play over and over until it just sinks into my brain!
