Most popular music piano sheets have two treble clef lines and then one bass clef line at the bottom, and I’m unsure how to play this kind of music.
I know how to play regular music when it simply just has two lines, one treble clef and one bass clef, but I’m unsure of how to play this music.
Thank you!! 
I think the top treble clef is for the vocals or possibly for another instrument; the pianist plays the bottom treble clef with the bass clef
