I teach piano and often a teacher has to write up arrangements to aid in teaching. Sometimes we have to come up with an arrangement to hold on to a struggling or bored student. There are so many wonderful sites that have great arrangements. I encourage musicians/teachers to search for them and use their offerings. These arrangements are not any better, but I do hope you find them original.
Please use these for only teaching your students or for your own enjoyment. Do NOT post these arrangements on your site, though it is okay to link to this site without posting an image of the arrangement.
