For a few years now I've been singing as soon as I separate from my body and it seems to have a wonderful effect of raising my vibration. Anything from Buddhist chants (where a chorus of monks chime in) to songs like "Amazing Grace" or "Nothing's going to change my world" by the Beatles to Dead Can Dance to "Separator" by Radiohead. I've tried many techniques and chanting or singing is the most effective in achieving positive results and the full song with accompaniment will chime in after you start singing. I've also heard original symphonies I wish I could remember upon waking. I highly recommend it!
