A Musical Software

In my computer, there is an interesting software called "LaLaSong."
This software was already installed when I bought this computer. When I start LaLaSong, there is a staff notation with a treble clef, meter, and keys. And left side of the window, there are some musical notes. I click the note I want and put it on the staff, then I can hear it by clicking the "play" bottom. If I put some notes, I can make a melody.
I found this program may be a year or two years long ago, and sometimes I used it. I used this program when I want to remember the score for some melodies which I don't have. But, often it's easier to check the notes by plucking violin before placing them on the staff.
It's really fun to do this.
But the only and the biggest regret for this LaLaSong program is this; I can't print the score I made!! How regrettable it is... but I don't feel to buy another software for only this. May be I'd better remembering all of them just in my head.
