Using Audacity Multi-Track free software to help you learn (Ted Blank's method) Many people have found the freeware program "Audacity" to be very helpful in learning your music. Audacity Is available for Windows, Mac and Linux.
I have created a document with screen shots showing how to install and use the program along with a YouTube video recording of a live training session where I demonstrated using the program to learn your part. The YouTube video can be accessed here while the PDF file of the training document can be downloaded at the bottom of this webpage. By loading the part-predominant track into Audacity you can do several things:
By panning the learning track full left, you can record yourself singing along with only your part, as in a 1-on-1 session with a teacher who knows your part.
By panning the learning track full right, you can record yourself singing along with the other 3 parts as in a quartet.
Also, after downloading and installing a free mp3 encoder (instructions are contained within Audacity) you can export an mp3 file of your best efforts and send it to someone to review.
Best of luck with your learning efforts! This tutorial was originally provided by Ted Blank. Thank you, Ted.
