TLDRThe transcript describes a free music theory lesson on compound intervals. A compound interval is over an octave and uncommon, usually up to a tenth. We convert large compound intervals to basic intervals by moving a note an octave up or down. The basic interval transfers to compound as it is plus seven. We invert compound intervals to basic intervals with a chart for minor to major or augmented to diminished. Homework is to draw 20 compound intervals, convert each to basic, and then invert each back to compound, practicing the process which is easy and systematic.

Takeaways
  • 😀 Compound intervals are intervals larger than an octave
  • 😯 To identify a compound interval, move one of the notes up/down an octave to make it a simple interval and add 7
  • 🤓 Compound intervals commonly go up to 9ths/10ths. Beyond that is rare
  • 😀 Perfect intervals stay perfect when compound
  • 🧐 To invert a compound interval, first identify the simple interval then invert using regular rules
  • 😊 Practice identifying, converting and inverting compound intervals
  • 🙂 Harmonic intervals move up/down vertically, melodic intervals move horizontally
  • 👍 Intervals and musical terms were the narrator's favorite exam sections
  • 😅 The narrator did not enjoy writing out scales
  • 😊 Hoped the lesson offered a break for viewers after some dense content recently
Q & A

  • What is a compound interval in music theory?

    -A compound interval is any interval that is above an octave, meaning larger than a perfect eighth. Compound intervals start at the ninth and can include larger intervals like a tenth, eleventh, etc.

  • Why are intervals above an octave called compound intervals?

    -Intervals above an octave are called compound because they contain more than one octave within the interval. This makes them sound fuller and more complex.

  • What is the difference between harmonic and melodic intervals?

    -Harmonic intervals move up and down between two notes sounding together, while melodic intervals move left and right between two notes played one after the other in a melody line.

  • How do you identify a compound interval?

    -To identify a compound interval, move one of the notes up or down by an octave to convert it to a basic interval that you recognize. Then add 7 to that interval number to name the compound interval.

  • If the basic interval is major, what will the quality be when it becomes a compound interval?

    -If the basic interval is major, the compound interval will also be major. Major/minor/perfect qualities stay the same when converting between basic and compound intervals.

  • What should you do before inverting a compound interval?

    -Before inverting a compound interval, first convert it to a basic interval to recognize what type of interval it is. This makes it easier to correctly invert the compound interval.

  • What happens to diminished/augmented intervals when inverting?

    -When inverting diminished intervals become augmented, and augmented intervals become diminished. The quality flips between those two.

  • What is the best way to get good at identifying intervals?

    -The best way is to practice identifying both basic and compound intervals through regular exercises. Over time you develop an intuitive sense of interval relationships.

  • What are some examples of compound intervals you may encounter?

    -Some common compound intervals are the major/minor ninth, major/minor tenth, major/minor eleventh, and occasionally twelfths.

  • Why does the instructor suggest doing homework exercises with intervals?

    -Doing homework exercises helps develop skills with intervals systematically. With practice, interval identification can become second nature and fun rather than difficult.

😀 Introduction to compound intervals

Defines compound intervals as intervals above an octave and explains that they are relatively uncommon. Compound intervals can be simplified by moving one of the notes up or down an octave to form a basic interval, to which 7 is added to determine the compound interval.

05:00
😃 Inverting compound intervals

Explains how to invert a compound interval by moving notes up or down octaves to form a basic interval, inverting that, and then determining the new compound interval. Gives an example of inverting a major 10th to a minor 6th.

10:02
📝 Compound interval homework assignment

Gives a homework assignment to practice working with compound intervals. Students should draw 20 compound intervals, convert them to basic intervals, and then invert each compound interval.

Keywords
💡interval
An interval in music refers to the difference in pitch between two notes. Intervals are important for understanding melody, harmony, and chord progressions. In the video, different types of intervals like harmonic, melodic, basic, and compound intervals are discussed. For example, a harmonic interval goes up and down, while a melodic interval goes left and right.
💡compound interval
A compound interval is any interval larger than an octave (8va). So intervals like a 9th, 10th, 11th etc. are considered compound intervals. They occur less commonly than basic intervals. To work with them, you can transpose the notes to convert the compound interval into a basic interval, making it easier to understand.
💡invert
To invert an interval means to flip it upside down - to put the top note on bottom and bottom note on top. This changes the interval quality (major becomes minor, augmented becomes diminished etc.). The video talks about techniques to invert both basic and compound intervals.
💡octave
An octave represents the pitch distance between one musical note and another with half or double its frequency. When inverting or transposing compound intervals, notes are shifted by octaves to convert them into simpler basic intervals.
💡transpose
Transposing means shifting a melody, chord progression or interval up or down in pitch. For compound intervals, one technique is to transpose one of the notes up or down by an octave to convert it into a basic interval, making it easier to understand.
💡chord
A chord is made of 3 or more notes played together harmonically. The video mentions how harmonic intervals relate to chords and harmony vs. melodic intervals that have notes played one after the other.
💡scale
A scale represents the set pattern of pitches used in a key. Though not discussed much, understanding scale degree names and patterns helps in identifying intervals between notes.
💡pitch
The pitch is how high or low a musical note or sound is. Intervals deal with the difference in pitch between notes. Changing the pitch by shifting notes up/down octaves or inverting them modifies the interval.
💡frequency
The frequency determines the pitch - higher frequency corresponds to higher pitched sound/note. Notes that are an octave apart have double (or half) the frequency. This allows easy transposition by octaves when working with intervals.
💡key
The key refers to the tonal center in a piece of music based on a scale/set of pitches. Though not elaborated much, the idea of musical keys and scale patterns relates to how intervals are perceived and used.
Highlights

Compound intervals are intervals above an octave

Harmonic intervals go up and down, melodic intervals go left and right

Anything above an octave is considered a compound interval

Convert compound intervals to basic intervals by moving notes up/down an octave

Add 7 to the basic interval number to name the compound interval
