  1. 01Tonality and the Origin of the Major ScaleNow that you know your intervals, let's see where the major scale comes from. You'll discover the role of resonance, of three generating chords and of the tonal notes, and what equal temperament changes.14 min
  2. 02The Names of the Scale DegreesBy the end of this lesson, you'll be able to name each degree of a scale by its function, in any key.5 min
  3. 03The TetrachordYou'll see how a major scale splits into two identical tetrachords, and why this lets one scale lead to the next.5 min
  4. 04Linking Scales: The Order of SharpsIn this lesson, you'll build all the major scales with sharps, one after another, and work out the order of sharps.8 min
  5. 05Key Signatures with SharpsYou'll learn to read a sharp key signature to find the key, and to write the key signature of a given key.6 min
  6. 06Linking Scales: The Order of FlatsNow let's turn to the flat side. You'll build all the major scales with flats and work out the order of flats.8 min
  7. 07Key Signatures with FlatsLet's finish with flat key signatures. You'll learn to read one to find the key, and to write the key signature of a given key.6 min
  8. 08The modes: major and minorIn this lesson, you'll learn to tell the major mode from the minor mode, by looking at where the half steps fall and at the two notes that define the mode.7 min
  9. 09How the minor scale is generatedHere you'll discover where the minor scale comes from and why its 7th degree is raised, and you'll learn to recognize its three forms.9 min
  10. 10Relative keysThis lesson shows you how to find the relative key of any scale, and which intervals occur in each mode.12 min
  11. 11Finding the key of a pieceAfter this lesson, you'll know how to tell, from a key signature, whether a piece is in the major key or in its relative minor.7 min
  12. 12Closely related keysYou're about to meet the five closely related keys of every key, along with a shortcut for finding them.6 min
  13. 13The chromatic scaleYou'll learn how to spell a chromatic scale correctly, going up and coming down, in a major or a minor key.9 min
  14. 14Enharmonic keysThis lesson explains how 15 scales come down to just 12 tones, and how that closes the circle of fifths.8 min
  15. 15ModulationBy the end of this lesson, you'll recognize a modulation and the note that brings it about, and you'll know how it is written.7 min
  16. 16TranspositionNow let's learn to transpose a passage, both in writing and at sight by changing clefs, while handling the accidentals correctly.15 min
