Just4Fun Publishing is constantly releasing qualitative sheet music for different instruments and voices which you can easily download and print out as many times as you need.
One of our aims is to provide amateur musicians with the easy versions of the most famous and the greatest music, no matter for which instrument or voice it was written originally.
Recently the famous Aria of Lauretta from opera Gianni Schicchi by Giacomo Puccini was published on this site. There are two versions available:
O mio babbino caro. Sheet music without lyrics in A flat major
and second is transposed to A major.
O mio babbino caro. Sheet music without lyrics in A major
The score is typeset from the vocal score, but the lyrics is omitted, because the lyrics is still copyrighted. The sheet music can be performed on any melodic instrument and piano. The file contains the score for soloist and accompanying piano, as well as the solo part.
If you know the words of this Aria, you can sing from this sheet music. If you don't know the words, you can easily find them in wikipedia.
