Piano octaving

[OCTO]

What is better notation to use, single or double?
It is a very long phrase, perhaps two pages like continues...

[John Ruggero]

Much better to do it like the first example. Only use octave signs when the notes would otherwise involve many ledger lines, especially in the lower staff.

[David Ward]

I'm glad you answered John. I was going to suggest the same as you, but much better from an experienced pianist (which I am not).

(I am assuming that this is for piano or at least keyboard of some kind.)

[tisimst]

Definitely agree with John.

[OCTO]

Many thanks. I indeed expected answer from John in the first hand!
