I Didn't Know Where CHORDS Came From Until I Knew THIS
Harmonizing a Major Scale and Creating Triads
Introduction to Harmonization
- The lesson focuses on harmonizing a major scale and transforming it into triads (or chords).
- Emphasizes the usefulness of this lesson for both personal enjoyment and academic purposes.
- Scales are described as essential ingredients for creating music, linking them to chords and arpeggios.
Understanding the C Major Scale
- The C major scale is chosen due to its simplicity, having no sharps or flats.
- The notes of the scale are numbered from root (1st note) to octave (8th note), highlighting that there are seven unique notes.
Creating Triads through Tertian Movement
- Triads are formed using "tertian movement," which involves skipping notes in groups of three.
- Example given: To create a C major chord, jump over D to collect E (the third), then jump over F to collect G (the fifth).
Building Other Triads
- Demonstrates how to build other triads by applying the same leapfrog technique across different root notes.
- Lists out the process for constructing various triads while maintaining clarity on each step.
Visual Representation of Triads
- Suggestion made to organize triad information in a table format for better visualization.
- Explanation of two types of thirds: major thirds (two steps apart) and minor thirds (one step plus one half-step).
Importance of Major and Minor Thirds
- Discusses the relationship between major and minor intervals, likening them to yin and yang concepts.
- A minor third is created by moving back one fret from a major third, emphasizing their contrasting nature.
Cycle of Thirds as a Tool
- Introduces the "cycle of thirds" as an important tool for transposing keys by adding sharps or flats.
- Mnemonic provided: "Every good band deserves fans and cash" helps remember key notes effectively.
Memorization Techniques
- Encourages creating personal mnemonics for memorization rather than relying solely on provided phrases.
- Stresses that mnemonics serve as temporary aids until mastery is achieved in recalling musical information.
Conclusion on Memorization
Understanding Chords and Roman Numerals in Music Theory
Introduction to Chords in C Major
- The discussion begins with the identification of chords in the key of C major, listing them as first through seventh chords. It emphasizes that Arabic numbers alone do not indicate whether a chord is major or minor, which is crucial for understanding chord quality.
Roman Numerals and Their Significance
- Roman numerals are introduced as a method to denote chord qualities. An uppercase numeral indicates a major chord (e.g., I), while a lowercase numeral signifies a minor chord (e.g., ii). This distinction is essential for music theory.
Building Triads
- The speaker transitions into building triads, specifically starting with the C major triad composed of notes C, E, and G. The distance between these notes is analyzed to determine their intervals.
- A triangle symbol represents "major" in shorthand notation, while a minus sign denotes "minor." This shorthand will be used throughout the analysis of intervals within chords.
Analyzing Intervals Between Notes
- The speaker fills out the cycle of thirds by identifying intervals between various notes:
- C to E = Major third
- E to G = Minor third
- G to B = Major third
- B to D = Minor third
- D to F = Minor third
- F to A = Major third
- A to C = Minor third
Extended Roman Numerals Explained
- Each triad's structure is broken down into root, third, and fifth components. For example:
- In the case of C major (C-E-G), it has a major third from C to E.
- Extended Roman numerals are discussed; they provide clarity on whether chords are major or minor based on their interval structures.
Example: D Minor Chord Analysis
- Moving onto the D minor chord (D-F-A), it’s noted that:
- D to F forms a minor third,
- F to A forms a major third,
This confirms that D-F-A constitutes a D minor chord.
Continuing with Other Chords
- The process continues with an analysis of other chords like E minor (E-G-B):
- E-G forms a minor interval,
- G-B forms a major interval.
Thus confirming its classification as an E minor chord.
- Finally, the F major chord (F-A-C):
- F-A results in a major interval,
- A-C results in a minor interval.
This leads us back into discussing how these relationships inform our understanding of extended Roman numerals.
Conclusion on Chord Qualities
Understanding Chord Structures and Their Relationships
Major and Minor Chords
- The distance between G and B is a major third, while the distance from B to D indicates a major chord structure. Thus, the root note G forms a G major chord.
- Analyzing A-C-E reveals that A to C is a minor third, and C to E is a major third. This pattern illustrates how major and minor chords alternate in their construction.
- The chord built on A is identified as minor due to its root note. Roman numeral analysis shows it as five (V) for the dominant chord.
Diminished Chords
- The B-D-F chord presents an unusual case; both intervals are minor thirds, leading to instability in sound due to the flattened fifth.
- The diminished fifth occurs when the perfect fifth interval is lowered by one fret, creating tension within the chord structure.
- Understanding diminished chords involves recognizing that they require specific notation indicating their diminished quality.
Triads Overview
- There are three major chords followed by three minor chords, culminating in one diminished chord. This sequence applies universally across keys beyond just C major.
- Primary triads consist of chords I (major), IV (major), and V (major), which are essential for establishing harmonic movement known as cadences.
Secondary Triads and Leading Notes
- Secondary triads include chords II (minor), III (minor), and VI (minor). These provide additional harmonic options but are less foundational than primary triads.
- The seventh chord is characterized as diminished, often referred to colloquially as "wobbly." Memorizing these structures aids in understanding guitar applications.
