Intro to Theory The Nuts & Bolts of Music Music Basics All sound is caused by vibration Parameters of Sound : – Pitch: How high or low a sound is. – Volume: How loud or quiet. – Duration: How long a sound lasts. • sustained vs. decaying – Timbre Musical Elements Rhythm: The timing of music – Pulse: a steady beat – Tempo: speed – Meter: Arrangement of beats in patterns- measures Melody: A series of tones forming a musical statement. Harmony: Two or more sounds happening at the same time. Usually as background. Form: Organization or structure of music. Texture: How the musical parts are woven together. Timbre (Tone): The unique individual characteristics of each sound. Music Notation Rhythmic value: How long a sound lasts – Whole note = 4 beats – Half note = 2 beats – Quarter note = 1 beat – Eighth note = ½ beat (usually in pairs) – A dot after a note extends its value by half. There is a corresponding rest for each note Music Notation The Staff: The five lines and four spaces on which music is written. – Each line and space has an alphabet name Clefs: Determines if the written notes will sound high or low. – Treble clef (G clef) – Bass clef (F clef) The Great Staff: A treble clef staff joined with a bass clef staff. The Piano Keyboard 88 keys – 52 white & 36 black – Black keys are in groups of 2 & 3 – White keys follow the musical alphabet ABCDEFGABCDEFGABCDEFG….. Two landmark keys are: – C: to the left of 2 black keys – F: to the left of 3 black keys Black keys are indicated by 2 symbols: – Sharp (#) This raises a key ½ step – Flat (b) This lowers a key ½ step Scales A scale is a series of tones in a row, usually made up of whole steps & half steps. – The most common scales are: Major scales Minor scales – Other scales include: Chromatic Whole tone Pentatonic Major Scales A major scale is made of seven notes (plus the octave) in alphabetical order. The notes are all a whole step apart except: – Between 3&4, 7&8 which are half steps A major scale is named by the starting and ending pitch. – Eg. C scale goes from C to C – F scale goes from F to F Major Key Signatures Key Signatures are sharps - # or flats – b written at the beginning of each staff. They tell you: – What notes are # or b throughout the piece, – The key or tonal center Reading Key Signatures For sharp keys: – Go up ½ step from the last sharp written For flat keys: – The next to last flat is the key One flat = Key of F Sharps & Flats are always written in a specific order – Sharps: Fat Cats Get Drunk At Every Bar Flats are in reverse order Intervals Intervals : The distance between two notes. – Melodic Intervals: One note at a time. – Harmonic Intervals: Two notes at once. – Arithmetic Distance: 2nd, 3rd, 4th, etc. – Interval Quality: There are 5 types: Perfect Major Minor Augmented Diminished Intervals In a major scale, there are only two kinds of intervals: – Perfect 1st, 4th, 5th, 8th – Major 2nd, 3rd, 6th, 7th Intervals Perfect intervals can become Augmented or Diminished – If the interval is # (raised ½ step) it becomes Augmented – If the interval is b (lowered ½ step) it becomes Diminished Intervals Major intervals can become Augmented or Minor – If the interval is # (raised ½ step) it becomes Augmented – If the interval is b ( lowered ½ step) it becomes Minor Minor Key Signatures Each major key has a relative minor key located 3 half-steps ( a minor 3rd) below. Relative Minor Keys: – Share the same key signature – Have the same notes in their respective scales – Have different roots Parallel keys have the same root, but different key signatures. Minor Scales Three types of Minor Scales – Natural: These use the same notes as the relative Major Key – Harmonic: The 7th note is raised ½ step – Melodic: The 6th & 7th notes are raised ½ step ascending and Natural descending Natural Minor Scales have half-steps between: 2&3, 5&6 Triads Triads are groups of 3 tones sounding simultaneously (chords) Triads are built using the 1st, 3rd, & 5th notes of the scale Four types of Triads: – Major – Minor – Diminished – Augmented Triad Construction You can build Triads by counting ½ steps from the Root: – Major: Root + 4 + 3 – Minor: Root + 3 + 4 – Diminished: Root + 3 + 3 – Augmented: Root + 4 + 4
