Major Scale, Key Signatures

Major Scale Formula

  • Question 1: Write the formula for a major scale using whole steps and half steps.
    • The major scale is constructed using a specific pattern of whole steps (W) and half steps (H).
    • Formula: W - W - H - W - W - W - H
    • Where:
      • W represents a whole step (two semitones)
      • H represents a half step (one semitone)
    • This pattern can be applied starting from any tonic (first note of the scale) to determine the major scale for that note.

Applying the Major Scale Pattern

  • After establishing the formula for the major scale, we will apply it to create specific major scales.

Questions 2 and 3: Writing Major Scales

  • Question 2: Write the major scale starting on E flat (Eb) for the treble clef.

    • E flat Major Scale:
    • Notes: Eb - F - G - Ab - Bb - C - D - Eb
    • Steps between notes according to the major scale formula:
    • Eb to F (W)
    • F to G (W)
    • G to Ab (H)
    • Ab to Bb (W)
    • Bb to C (W)
    • C to D (W)
    • D to Eb (H)
  • Question 3: Write the major scale starting on A for the bass clef.

    • A Major Scale:
    • Notes: A - B - C# - D - E - F# - G# - A
    • Steps between notes according to the major scale formula:
    • A to B (W)
    • B to C# (W)
    • C# to D (H)
    • D to E (W)
    • E to F# (W)
    • F# to G# (W)
    • G# to A (H)

Solfege Syllables

  • Question 4: Write the solfege syllables for a particular tune.
    • Note: The specifics of the tune were not provided, but solfege syllables correspond to the notes of the scale using:
    • Do, Re, Mi, Fa, Sol, La, Ti, Do
    • Solfege is effective for ear training and sight-singing exercises.

Identifying Key Signatures

  • Final task according to the instructions:

    • Identify two key signatures in treble clef and two in bass clef.
    • Discuss how to deduce the key name from each signature:
    • For treble clef:
      • Example: If a key signature has one sharp, it is in G Major or E minor.
    • For bass clef:
      • Example: If a key signature has two flats, it is in B flat Major or G minor.
  • Students are provided with key signatures to analyze and identify the corresponding major/minor key based on the count of sharps/flats.
