Chord Variations in Four Parts - Music Theory
TLDRThe video explains basic diatonic chords and extended chords. It first covers how to build basic triads using the scale degrees in a key. It then shows how to expand triads into richer extended chords by adding extra notes like the 7th, 9th, 11th, and 13th on top. Several example chords are analyzed, identifying if they are basic triads or extended chords. Both the standard roman numeral names and popular chord names are used. Extended chords can create beautiful new colors, but writing them in 4 parts often requires omitting the 5th. Overall, the goal is to get more creative using diatonic and extended chords when composing.
Takeaways
- 😀 There are basic diatonic chords that come from the notes of a scale, as well as extended chords with added notes
- 👍🏻 Chords can be described by Roman numerals based on their order in a scale or by their root note names
- 🎹 Extended chords add extra notes like sevenths, ninths, elevenths, and thirteenths on top of basic triads
- 🎼 In a 4-part arrangement of extended chords, sometimes the fifth is omitted to avoid too many notes
- 🤓 Identifying chords involves finding the root, third, and fifth notes and noting if they are major, minor etc
- 😮💨 Diminished chords have a minor third and diminished fifth, augmented chords have a major third and augmented fifth
- 🎵 Minor ninth chords add more color than plain major ninth chords
- 👂🏽 Chord spacing changes the sound quality even if it has the same notes
- 📝 Figuring out chords from notes on a page builds skills in using diatonic and extended chords creatively
- 🙌 Experimenting with different chords creates richer and more interesting harmonies
Q & A
What are diatonic chords?
-Diatonic chords are the basic chords that are built from the notes of a major or minor scale. They include the I, ii, iii, IV, V, vi, and vii chords.
How do you build a diatonic chord?
-To build a diatonic chord, start with a note of the scale, like C. Then add the 3rd and 5th notes above it, like E and G. This forms a chord triad.
What are some ways to extend chords?
-You can extend chords by adding extra notes on top, like a 7th, 9th, 11th, or 13th. This creates richer, more colorful chords.
How do you identify an extended chord?
-If a chord has 4 different notes, it is likely an extended chord. Look for the basic triad then identify the added extensions like the 7th or 9th.
What notes can you omit when voicing extended chords in 4 parts?
-When voicing extended chords in 4 parts, you can omit the 5th to make room for the extensions. So you may have the root, 3rd, 7th, and 9th for example.
What is the difference between a major 9th and minor 9th chord?
-A major 9th chord has a major 3rd and a minor 9th chord has a minor 3rd. So G9 would be major and Gm9 would be minor.
How can you create more interesting chord progressions?
-You can make chord progressions more interesting by using extended chords, borrowing chords from parallel keys, using secondary dominants, modal interchange, and chromatic mediants.
What Roman numerals are used for diatonic chords?
-In major keys, the diatonic chords are labelled with Roman numerals I, ii, iii, IV, V, vi, vii° based on their scale degree.
What are some tips for identifying chords by sight?
-Look for the root of the chord first. Then identify if the 3rd is major/minor and the 5th is perfect/diminished/augmented. See if there are any extensions like a 7th.
How can you experiment with different chord voicings?
-You can experiment with voicings by changing which notes are in the bass, alto, tenor, and soprano parts. This changes the spacing and sound of the chord.
Outlines
😀 Introducing basic and extended chords
The paragraph introduces basic diatonic chords that can be formed from the notes of a scale, as well as extended chords which add additional notes on top of the basic triads. Examples of extended chords include major 7th, 9th, 11th, and 13th chords.
😊 Identifying sample chords
The paragraph analyzes 10 sample chords provided, identifying each one in terms of its chord name and quality (major, minor, diminished etc.). Both basic diatonic chords and extended chords are covered.
😁 Comparing similar ninth chords
The paragraph compares two D ninth chords, one minor and one major, analyzing the difference in quality between them based on the notes used.
