You want to play that tune you like on your saxophone? What are the chords to that one song? Do you need sheet music for a melody you made up? Any melody or progression you want, I'll put it down in perfectly notated, easy-to-read sheet music and send it to you in one of several standard file formats.
Is the melody just a short jingle or loop? I may choose to offer you multiple gigs for just one payment! All you need to do is ask!
I recommend you contact me before buying to ensure that your melody or progression is acceptable. If it is a lot of work, I may ask for more payments for the same job. However, I have so far not turned away any customers! If you have questions about anything, just message me. I am a human being after all! And I ALWAYS leave positive customer feedback!
