Can arduino control tones on 8 different Piezo speakers?
found 3 tones tutorial
any solution for 8 tones on 8 speakers?
you could take a look at this page:
It tells how to use tone() to play different notes on multiple outputs!

what is the max number of piezo speaker can be used to play music?
are you planning on having them playing SIMULTANEOUSLY?
I had this idea for playing 13 notes simultaneously, don't know if it will work.
May have to shorten a bit for a '328 board, mostly because there are fewer pins.
Heavy Edit - Got rid of all the stuff that didn't work.
See this link for working code, schematic, and protoboard layout to play 13 notes simultaneaously.
(only wired up 8, all I had switches for)

yes
1 speaker per channel
"what is the max number of piezo speaker can be used to play music?"
The Arduino Due has 54 digital outputs. You can play all of them if you have piezo speakers that draw a small current, like 1mA each.
i = c dv/dt
c of piezo speaker is...
c = 1mA x .001 second / (3 volts) = .33uF Maximum
Do you have the arduino board now working?
How many piezo speaker have you hooked up, and heard sound from?
