As we learned previously, notes that have stems can have their stems go either up or down. Choosing the direction can be a bit complicated, but there are some general best practices for choosing stem direction that we will adopt for this course. Thankfully, when using notation software, these rules are applied automatically, but we should also be able to write notation by hand when necessary. Our first rule
is that the stem is placed on the right side of the notehead when the stem goes up, and the left side of the notehead when the stem faces down, this is always the case. Our second rule
is more general: when the notes appear below the middle staff line, the stems go up, when the notes appear on or above the middle line, the stems go down. This rule has the benefit of keeping as much of the stem inside the five-line staff as possible.
