We're excited to share our latest addition to uTheory's lessons: Octave Numbers!

In this lesson students learn to write and identify notes in specific octaves, using International Pitch Notation/Scientific Pitch Notation system, which labels middle C as C4.

Learning Outcomes:

Students completing this lesson will be able to:

  • Identify where middle C is on the piano, treble clef and bass clef staffs,
  • Write notes in the specific octaves in the treble clef and bass clef staffs,
  • Understand the relationship of accidentals to note naming with octave numbers.

New Skills:

This lesson also introduces several new skills, which you may wish to include in your classes (by setting checking the skill), or set to optional (unchecking the skill) to allow students to practice, but not count towards their grade. (You can hide skills by clicking until you see an eye with a slash through it.)

You can find these by going to uTheory Teach Classes ... Choose Skills Pitch & Harmony. Under Treble Clef you'll need to check "Treble Clef Octave Numbers," and under Bass Clef, check "Bass Clef Octave Numbers."
