Q & A

What are the two main topics covered in this music theory lesson?
-The two main topics covered are inharmonic changes in intervals and inverting intervals.
What is an interval chart and what information does it provide?
-An interval chart shows the number of semitones that make up different intervals. It provides information on the various types of intervals like minor, major, diminished and augmented.
How do you augment or diminish an interval?
-To augment an interval, you add a flat to the bottom note to expand or increase the gap between notes. To diminish an interval, you add sharps to the top note to bring the notes closer together.
What happens when you invert a major interval?
-When you invert a major interval, it automatically becomes a minor interval. For example, inverting a major 3rd makes it a minor 6th.
What is an inharmonic change in an interval?
-An inharmonic change means changing one note of the interval to another note name that is the same pitch. For example, changing C to B#.
What options do you have when making an inharmonic change?
-You can move the top or bottom note of the interval up or down to its inharmonic equivalent.
What happens to perfect intervals when inverted?
-Perfect intervals remain perfect when inverted. For example, a perfect 5th inverted is still a perfect 5th.

Keywords

💡Intervals

Intervals are the distance between two pitches or notes in music theory. In the video, the concept of intervals is explored in depth, with a focus on understanding their basic types, how they are inverted, and their inharmonic changes. Examples include perfect firsts, major thirds, and augmented seconds, illustrating the fundamental role intervals play in constructing melodies and harmonies.

💡Inharmonic changes

Inharmonic changes refer to the phenomenon where two different note names (such as C# and Db) refer to the same pitch, depending on the musical context. The video discusses how these changes affect intervals, demonstrating that the same sound can be notated in different ways, affecting the interval's classification. This concept is crucial for understanding how music can be transcribed and interpreted differently.

💡Inverting intervals

Inverting an interval involves flipping the positions of its notes, changing the lower note to be higher than the other, or vice versa. The video explains that inverting intervals changes their quality (major becomes minor, augmented becomes diminished, and perfect intervals remain perfect), which is a vital skill for composing and understanding musical structures.

💡Interval chart

An interval chart, as introduced in the video, is a visual tool that helps to understand the relationship between different intervals and their semitone counts. It maps out basic intervals up to an octave, and explains compound intervals beyond an octave. This chart is instrumental for learners to grasp the concept of intervals and their respective semitone distances.

💡Semitones

Semitones are the smallest unit of pitch used in Western music, equivalent to the distance between two adjacent notes on a piano. The video uses semitones to explain the size of intervals, showing how many semitones make up various intervals, from a perfect first (0 semitones) to a perfect octave (12 semitones). Understanding semitones is essential for analyzing and constructing musical intervals.

💡Diminished and Augmented intervals

Diminished intervals are smaller than minor or perfect intervals, while augmented intervals are larger than major or perfect intervals. The video highlights how altering intervals by adding or removing semitones can change their quality to diminished or augmented, illustrating the flexibility and complexity of interval relationships in music theory.

💡Major and Minor intervals

Major intervals are those that are generally considered to have a 'larger' or 'brighter' sound, while minor intervals have a 'smaller' or 'darker' sound. The video discusses how inverting intervals can change a major interval to a minor one and vice versa, emphasizing the importance of these concepts in understanding and manipulating musical harmony.

💡Perfect intervals

Perfect intervals, including unisons, fourths, fifths, and octaves, retain their 'perfect' quality even when inverted. The video explains that perfect intervals are unique because their inversion does not change their perfect quality, unlike major/minor or augmented/diminished intervals, underscoring a fundamental property of these intervals in music composition.

💡Compound intervals

Compound intervals extend beyond an octave, such as a ninth (an octave plus a second) or a tenth (an octave plus a third). The video mentions that while the current lesson focuses on simple intervals within an octave, compound intervals will be explored in future lessons, highlighting the layered complexity of musical intervals.

💡Homework exercises

The video concludes with assignments designed to reinforce the lesson's concepts, including inverting 20 different intervals and writing out 20 intervals with inharmonic changes. These exercises aim to solidify the viewer's understanding of interval inversion and inharmonic changes, emphasizing practical application of music theory concepts.
