  1. Thursday, September 22, 2011 Introductionto music theory

  2. TODAY: • Music Sharing – Peter (XHS) • Turn in: • L32 & L33 • RQ7 • Noteflight – Do you have an account? Issues? • Review Intervals • The Circle of Fifths • The Circle of Fifths project • ET8

  3. INTERVALS: • An INTERVAL in music is the distance in pitch between two notes. • An interval is counted from the lower note to the higher note, with the lower note counted as 1 (count every line and space going up the staff). • Intervals are names by the number of the upper note (2nd, 3rd, 4th, 5th, 6th, 7th) with two exceptions: • The interval that is between notes that are identical is called a UNISON (unis.) (or a prime).

  4. INTERVALS: An interval of an 8th is called an octave (8va). Melodic intervals are sounded separately. Harmonic intervals are sounded together. Even numbered intervals (2nd, 4th, 6th, 8va) are written from line to space or space to line. Odd numbered intervals (unis., 3rd, 5th, 7th) are written from line to line or space to space. Two note combinations are also known as dyads. We will eventually “qualify” intervals by type, as well as distance (major, minor, diminished, augmented, perfect).

  5. THE CIRCLE OF FIFTHS: • The CIRCLE OF FIFTHS is useful in understanding scales and key signatures. • It shows the relationship of one key to another by the number of sharps or flats in the key signature and the order in which those sharps or flats occur. • More specifically: • It shows the relationships among the 12 tones of the chromatic scale, their corresponding key signatures, and the associated major and minor keys.

  6. THE CIRCLE OF FIFTHS: • Sharp keys go clockwise in ascending tetrachord order. • Flat keys go counterclockwise in descending tetrachord order. • The sharp keys ascend by 5ths (or descend by 4ths). • The flat keys ascend by 4ths (or descend by 5ths).

  7. ORDER OF SHARP KEYS: • C (no sharps) • G (1 sharp – F#) • D (2 sharps – F# & C#) • A (3 sharps – F#, C#, G#) • E (4 sharps – F#, C#, G#, D#) • B (5 sharps – F#, C#, G#, D#, A#) • F# (6 sharps – F#, C#, G#, D#, A#, E#) • C# (7 sharps – F#, C#, G#, D#, A#, E#, B#)

  8. ORDER OF FLAT KEYS: • C (no sharps) • F (1 flat – Bb) • Bb (2 flats – Bb & Eb) • Eb(3 flats – Bb, Eb, Ab) • Ab(4 flats – Bb, Eb, Ab, Db) • Db (5 flats – Bb, Eb, Ab, Db, Gb) • Gb (6 flats – Bb, Eb, Ab, Db, Gb, Cb) • Cb (7 flats – Bb, Eb, Ab, Db, Gb, Cb, Fb)

  9. EXAMPLES:

  10. EXAMPLES:

  11. THE CIRCLE OF FIFTHS PROJECT: • Create your own Circle of Fifths design, preferably in 3D format. • Think of this as creating your own prototype for a product you wish to sell to eager musicians! • It should be constructed creatively and cleanly (you should not just use a pencil and notebook paper)! “Think outside the box!”

  12. THE CIRCLE OF FIFTHS PROJECT: • It must be a CIRCLE (or some variation of a circle). • It must include all MAJOR keys. • It must include all numbers relating to key signatures. • Worth 100 points (project grade category) • DUE: Monday, October 3!
