Piano/Keyboard Synthesizers

Dynamic Markings

If both hands have the same dynamic markings, it suffices to just write the marking for the right hand.

8va and 8vb Lines

8va and 8vb lines are usually reserved for piano/keyboard. If a part is too high or low to be read comfortably especially if there are jumps, you can use a 8va or 8vb line accordingly.

Pedal Markings

By default, pedal markings for sustain are not necessary; it is understood that one re-pedals at the change of a chord. If chord change is ambiguous or unclear, or that there is a more specific pedaling, then feel free to put in the markings.

If you are using pedals, use pedal lifts and lift again like thus:

Different Sounds (Keyboards/Synth)

Use the Technique Marking to indicate what instrument/sound the keyboard is playing.
