If you want to post a music sheet produced in a word processor:
Open the file in a word processor and save as or print as a pdf, which usually saves to the local drive
drag the file to your google drive folder containing your music sheets to share
share the pdf to everyone (viewing unrestricted - anyone with the link can view)
copy the URL of the freely shared file
on the home page add a title line for the song in the alphabetic position with the standardized format (e.g., 'Give Yourself to Love - Kate Wolf - 1982 (key C)') [if this is just a second key or alternative version of the song - simply add a new line - later a song sub-page can be added to consolidate the multiple versions of a song and leave only a single line on the home page].
Select the entire line and then convert to text type 'Heading'
Select the title only, click the insert link tool in the toolbar, then paste
The change is not fully complete for all viewers and editors until you click the 'Publish' button.
