Arrangement Question

[Rizzo]

I have a piece of sheet music in which the same key in the treble & bass clefs is supposed played at the same time (see example below). This occurs numerous times in the piece. I find this confusing. Why was this written this way? How should this be played? Thank you so much for your help.

Sometimes it is because the transcription of organ sheet to piano sheet..

 

[Rizzo]

Hmm...that makes sense. I wonder why the transcriber didn't make the corrections. Thank you.

Look! Here are sheets for organ and the same for piano. Sheet for organ looks more clear May be your half-note G is for pedal keyboard?

 

[Rizzo]

Possibly so. I just never came across something like this.
