Many of you are here because you saw the video of me singing Crosby, Stills and Nash's Helplessly Hoping
...all 3 parts! If you haven't seen the video, and listen to a few other harmony demos, here:
Record Yourself Singing Harmony
To find out how to start doing this yourself, see the post here: Sing Harmony With Yourself - Learn How To Record Your Voice On Your PC And Sing Along With It!
We also have a course on recording harmony - either with yourself or with other people. It shows you how to do it the old fashioned way of course - recording voices on different tracks and mixing them all together. But the course also shows you how to use software to split your own voice into multiple parts and generate the harmony for you.
That course is Harmony Recording Awesomeness. Visit this page to find out more about it.
