Perfect Fifths Writing

Perfect Fifths

In the next set of lessons, you will see a perfect fifth lit up on your instrument and you will write it in music notation.

Like other perfect intervals, both notes will usually have the same accidental.

For example, if the bottom note is sharp, the top note will be sharp too.

Or, if the bottom note is flat, the top note will be flat too.

The one exception is when starting on B or Bb because B is 7th degree of the C scale.

As we learned earlier, a fifth built on this note will come out flat.

Therefore, if the bottom note is B, the top note F would require a sharp. Or if Bb, is used, then F would be natural.
