As of today, brucepaine.co.nz has a new section entitled PDF Sheet Music which offers a selection of sheet music titles available for download via the Lulu publishing web site. At this point just a few titles are listed but these will be gradually added to over the coming weeks.
Lulu allows you to preview the first few pages of titles you may be interested in, allowing the option of trying some of the music before committing to a purchase.
The great advantage of purchasing PDF downloads is there's no need to wait for delivery and you can get to work on the music straight away. You will also avoid the cost of postage and packaging, and in most cases the PDF prices are less than the printed sheet music.
