Question on how to play a double note.

[MalcolmAmos]

Using this sheet music I found I had several revelations and a question.

Now my question; In the 17th and 18th measure, what is the accepted way for the bass to play this double note? I'd just play a C note in 17th and a D note in 18th and move on. I guess I'm having trouble deciding how I would sound a double note.

First time I've run across that. Need to get that into my bag of tricks.

Thanks,

This is a keyboard part and I'd leave these close interval double notes to the keyboard player - Just play the root alone. These sort of things work fine on the piano, but sound "muddy" on other instruments!!. My rule of thumb is never to play any double stop smaller than a third where the bottom note is on the stave :-).

If you want to chek it out, remember that Bass sounds an octave lower than written, so take it up and octave and try it there. I'd leave out the Bb/Cs and the C/Ds though!!.
