If a piano sheet has three lines, which two do i play if I want the melody?

Do I play the top and middle line? Or the top and bottom line?If a piano sheet has three lines, which two do i play if I want the melody?
The top line will generally be the melody line for a solo voice or instrument. The bottom two lines should be the treble and bass lines for the piano accompaniment. Sometimes the treble clef piano line will duplicate the vocal solo in which case you could just play the two piano lines.





If this is not the case then you can play the top (vocal) line with the piano bass (bottom) line. If you do this you may need to fill in some of the harmony notes that are in the piano top (treble) line.





Musician, composer, teacher.If a piano sheet has three lines, which two do i play if I want the melody?
Sometimes the melody is included in the accompaniment part.





But sometimes it is just ';accompaniment'; chord patterns.





If you are not playing to back up a singer and you want the melody included: play the upper vocal line and the bass clef of the piano part. If the bass part is too ';thin'; you may need to improvise to thicken it up a bit.
Let me guess a Vocal/Piano score.





... I'd leave the vocal line for the singer.
