This question came up from Proper chord tremolo notation and execution:
What is a proper way to notate a chord tremolo with bars (as opposed to writing it out explicitly), when the tremolo lasts more than one measure?
Three possibilities were suggested, shown in the picture below.
- Tie the entire chord across the bar lines and include the tremolo notation in between.
- Notate one part of the chord in one bar and the other part in the next bar, with tremolo notation in between.
- Notate the tremolo separately within each bar.
