TLDRThe video provides tips for harmonizing a repeated melody note, which can seem monotonous. It first explains the three diatonic chords that contain that note - as the root, third, or fifth. It then demonstrates embellishing techniques to keep interest despite the repetition, like chromatic neighbor tones, suspensions, secondary dominants, and extended chords. The goal is to distract from the repetitive melody by adding harmonic color and movement underneath it.

Takeaways
  • ๐Ÿ˜€ Repeated melody notes can make harmonizing tricky, but there are solutions
  • ๐Ÿ‘ Use the 3 diatonic chords that fit the repeating note (I, IV, VI)
  • ๐Ÿ’ก Alter chords with extensions, suspensions & chromaticism for interest
  • ๐ŸŽต Keep the bassline moving with passing tones to distract from repetitions
  • ๐ŸŽน Use chord inversions to revisit chords without being too repetitive
  • ๐Ÿ˜Š Borrow chords from the parallel minor key for color
  • ๐Ÿ”‘ Think of the repeating note as part of a secondary dominant for modulation
  • ๐ŸŽผ Add interest with chromatic neighbor tones & voice leading
  • โœจ Extend chords to 9ths & 11ths for a juicy final cadence if you're feeling brave
  • ๐Ÿค“ It's unlikely you'll need to harmonize 8 repeated notes, but same ideas apply for 2-3 notes
Q & A
  • What is a key challenge many people have with harmonizing melodies?

    -When melody notes repeat, people often struggle with how to harmonize them without just repeating the same chord. It can make the harmony feel 'stuck'.

  • What are three diatonic chords that can harmonize a repeated melody note?

    -The diatonic chords that contain that melody note - for example if the melody note was C, the chords would be C major (chord I), A minor (chord VI) and F major (chord IV) in the key of C major.

  • How can chromatic notes like passing tones help harmonize repeated melody notes?

    -Adding chromatic passing tones in the bassline or inner voices keeps the harmony moving and distracts from the melodic repetition, adding harmonic interest.

  • What options are there for harmonizing a longer repeated melody note?

    -You can revisit the chord in an inversion, use chromatic neighbor tones, hint at a new chord with chromatic notes, or add embellishments like suspensions to bring more harmonic color.

  • What is an example of a secondary dominant used in the example?

    -The Ebmaj7 chord moving to Abmin uses a D-flat to temporarily tonicize Ab as a secondary dominant.

  • What type of suspension is used and how does it work?

    -A 9-8 suspension is used, where the suspended B-flat delays resolving down a step to the A-flat, providing harmonic tension before resolving.

  • What chord extensions are used in the final cadence V-I and why?

    -The V11 chord builds tension through added extensions before resolving to the I chord. The flat 9 adds extra chromatic color too.

  • Why use so much chromaticism and chord extensions?

    -It adds harmonic interest and color to distract from the melodic repetition, keeping the listener engaged.

  • What are some simpler options for harmonizing repeats?

    -Use just the three diatonic chords, chromatic passing tones, or borrow chords from the parallel minor key. Only use more advanced harmonies if you want to.

  • What is the main takeaway or lesson on harmonizing repeats?

    -There are multiple harmonic options for adding interest under a repeated melody note, from simple diatonic chords up to advanced chromaticism and extensions.

๐ŸŽถ Exploring Chord Variations for Repeated Melody Notes

Gareth Green addresses a common musical challenge: harmonizing repeated melody notes without becoming monotonous. He introduces the concept of utilizing diatonic chordsโ€”chords within the keyโ€”to add variety. Using the note C as an example, he explains how it can serve as the root, third, or fifth of different chords in the key of C major, offering three distinct harmonic options (I, VI, IV). He extends the idea to include the note acting as a seventh in a chord, opening up further possibilities before considering chromatic chords for additional color. Gareth aims to demonstrate these concepts through a melody comprised of repeated E-flats, showing how to maintain harmonic interest and movement.

๐ŸŽน Advanced Harmonic Techniques for Repetition

In this section, Gareth delves deeper into sophisticated harmonic techniques to handle repeated notes, specifically focusing on a melody with repeated E-flats. He discusses the use of diatonic chords in E-flat major (I, VI, IV) and introduces inversions to diversify the harmony further. Gareth also explains how adding chromatic lower neighbor tones or auxiliary notes can create intriguing harmonies that distract from the repetition. Additionally, he illustrates the concept of a secondary dominant and its role in transitioning between keys, adding further color and complexity to the harmony. This approach shows how varied harmonic techniques can effectively enhance repeated melody notes.

๐Ÿ” Incorporating Chromaticism and Suspensions

Gareth continues to explore harmonic creativity by introducing chromaticism and suspensions to enrich the musical texture. He uses a D-flat to transition into a dominant seventh chord, which leads to an A-flat major or minor chord, showcasing secondary dominants and the use of borrowed chords from parallel keys. A 9-8 suspension adds another layer of interest, emphasizing dissonance resolution and further diverting attention from the repeated E-flats. This approach exemplifies how chromatic elements and suspensions can add depth and complexity to harmonization, making repeated notes more engaging.

๐ŸŽ‰ Creative Cadences and Extended Chords

In the final paragraph, Gareth explores the use of creative cadences and extended chords to conclude the harmonization of repeated notes. He suggests a V11 to I cadence, utilizing a flattened ninth for added spice. This technique demonstrates how extending chords and incorporating chromatic alterations can produce a rich, colorful harmonic progression. Gareth emphasizes that while not all techniques must be used simultaneously, they provide a toolbox for composers to keep music interesting, even with repeated notes. The video concludes with an invitation to further explore musical concepts through the Music Matters community.

Keywords
๐Ÿ’กHarmony
Harmony refers to the chords that accompany a melody. The video discusses techniques for harmonizing melodies, especially when melody notes repeat. As Gareth says, "You can harmonise a given part, like a melody, but what happens when the melody notes repeat?". The goal is to creatively harmonize repeating melody notes to avoid sounding "stuck".
๐Ÿ’กChromatic
Chromatic notes or chords use pitches outside the key signature. For example, Gareth introduces an A-natural over an E-flat major chord, creating chromatic dissonance. This adds harmonic color and interest. Chromatic chords distract from repetitive melody notes.
๐Ÿ’กCadence
A cadence creates a sense of closure, often through a V to I chord progression. At the end, Gareth harmonizes the final two repeating E-flats using a colorful V11 to I cadence to avoid sounding stuck.
๐Ÿ’กInversion
An inverted chord has a note other than the root in the bass. After using E-flat major triads, Gareth introduces first inversion E-flat major to sustain interest and keep the bass line moving.
๐Ÿ’กSuspension
A suspension involves delaying the resolution of a dissonant note to create tension. Gareth uses a 9-8 suspension in the A-flat minor chord, suspending the third (C-flat) before resolving it to B-flat.
๐Ÿ’กPassing Tone
A passing tone is a non-chord tone that connects two chords by step. For example, Gareth uses passing tones in the bass to connect I to VI and VI to IV chords.
๐Ÿ’กParallel Key
Parallel keys, like A-flat major and A-flat minor, share the same tonic. After a V7 in A-flat major, Gareth surprises the listener by instead using the parallel minor tonic chord.
๐Ÿ’กSecondary Dominant
A secondary dominant is a V chord from another key that resolves to a chord in the home key. The D-flat makes the E-flat chord a secondary dominant in A-flat that resolves to IV instead of I.
๐Ÿ’กNeighbour Tone
A neighbour tone is a nonchord tone a step away from a chord tone that is approached and left by step. Gareth uses chromatic lower neighbour tones on beat 4 to avoid rhythmic stagnation.
๐Ÿ’กEmbellishment
Embellishments like neighbour tones, suspensions, and chromaticism are used to creatively harmonise repeated melody notes, adding interest and avoiding stagnation.
