1. Piano Pronto: If you follow the work of Jennifer Eklund (https://pianopronto.com/), I'm sure you're familiar with the piece "End Game." This is one of those special pieces that students want to keep playing over and over again! I enjoy how it teaches to play in C minor, cross over hands, introduce ABA format, and pedaling. Whether my student is 6 or 60, everyone loves to play this one. Jennifer Eklund began writing under the name Piano Pronto in 2008. Now, she includes a "composers community" where others music is sold, too. Piano Pronto features arrangements of popular tunes, method books, supplemental songbooks, and a collaboration with Theory Time.
You can purchase hard copy books for students or purchase individual / studio licenses for PDF downloads. She also has weekly freebies you can access here: https://pianopronto.com/sheet-music/free-sheet-music/.
Forrest Kinney was a beloved educator, author, pianist, composer, and presenter. I had the joy of hearing his "Four Arts of Music" workshop at my local music teachers association chapter meeting. He passed away in December 2019 after a lengthy battle with cancer. His life’s mission was to help musicians become well rounded and able to enjoy what he called the Four Arts of Music: improvising, arranging, composing, and interpreting. I love this quote of his,“Now is the time—and it will always be the time—to be inspired and to create.”
My favorite books of his are Puzzle Play, Pattern Play, and Create First.
3. Musicnotes: https://www.musicnotes.com/
Whether you're looking for a hymn arrangement, Star Wars, or Christina Aguilera, this site has it all! I've had students look through this site and choose a new piece they'd like to learn in this time. I appreciate the variety on this site and ability to find just the right arrangement! There are over 300,000 arrangements to purchase and download PDF copies instantly.
4. IMSLP: https://imslp.org/wiki/Main_Page
Lastly, I want to share about the IMSLP Petrucci Music Library. If you're looking for a piece that is public domain (like Beethoven) this is a great place to find a copy of a piece.
I'd love to hear from you if there is a site where you've enjoyed finding new music!
