Notes 1 and 5 Introduction.

This is your first step of playing a note other than the tonic note of the chord (remember octaves are the same letter name). 5ths are a very safe alternate note, so you can play them pretty much anywhere throughout the bar, however, we usually reserve the first note in the bar for the tonic note. But remember, there are no hard and fast rules, so experiment and use your ears to identify what sounds good.
