'Voice Building' is one of the most popular vocal exercise programs from the UK. First released in 1988 on cassette, it has enjoyed a bestseller position over the years amongst contemporary singers. The exercises are often challenging, but they are always fun and uplifting to work on. The exercises are all sung in the first section, progressing through various keys. In the second section, there are the instrumental versions of the exercises, so the listener can focus more intently on their voice. There is also a section on aural (listening) tests in the latter part of the recording.
