About “But I Do (I Don't Know Why)”

What key is "But I Do (I Don't Know Why)" by Clarence "Frogman" Henry played in?

Is this the same notation a piano teacher would hand me?
Yes — "But I Do (I Don't Know Why)" is rendered at engraver quality (the Verovio engine, the same toolkit RISM and OpenScore editions use) from the original publisher MusicXML. You get standard piano notation: treble + bass clefs, key signature C, time signature, beams, dynamics — everything a printed sheet music book would have. Great for piano students learning to read music properly.
What's the difference between Sheet Music and the other modes here?
Sheet Music is the "classic" view — the one your piano teacher uses. Other modes (Beginner, Fall Down, Simple Sheet, Lead Sheet) trade real notation for color-coded notes and falling shapes to help absolute beginners. Use Sheet Music once you're ready to read both hands at once from real notation.
Can I practice from this view at my own pace?
Yes — slow the tempo from 120 BPM down (or up) without changing the pitch. The score scrolls in time and the currently playing note is highlighted, so you can drill a tough bar at half speed and bump it up once it feels comfortable.
Why can I click a note in the score?
Every notehead is interactive. Click and the audio jumps to that moment so you can drill a specific phrase or bar instead of replaying from the top. The currently playing note is highlighted as the music advances so your eye never loses its place.
Can I download the sheet music as a PDF?
Yes — Sheet Music PDF is one of the download formats for this song. The engraved score prints page-perfect on A4 / Letter so you can practice from paper as well as on screen.
