Personally, Basic Intervals are way to advanced for almost all guitar players. If fact, it is easy to understand if you are: A. excellent at mathematics. B. a focused dedicated studier, and C. plan on playing music in a band or orchestra. For 90 percent or more beginners, of any age, this subject is not necessary or importnat to the early phases of beginning guitar lessons. It may never be important to you. If you are here for said reasons, to learn basic intervals, read my guitar lesson reviews after you read this.
An interval is the musical distance between two tones. Expressing the relationship of two notes only. Which is commonly called polytonality, or may be referred to as bitonality. A melodic musical interval is being made when you play two notes, one after the other successively. And a harmonic interval is made when the notes are being played at the same time, like a chord.
Intervals allow the timing of written music to be even more precise. Which is the main reason to learn and understand intervals. Essentially this lesson covers the size differences in intervals. A large interval is called ‘far apart’ in distance between notes, and a small interval is called ‘close together’. The more complicated the music, the more important intervals become.
Intervals come in various sizes: Unison, second, third, fourths, fifths, sixths, sevenths, octave. Intervals that take up eight positions on the 5 line staff between them are called an octave. If the interval is between the 8 positions on the staff, it is in the same octave. Intervals that use more than 5 lines are called compound intervals.
Compound intervals are greater than one octave. Which includes ninths, tenths, elevenths and thirteenths as examples of compound intervals. Imagine that a compound interval has a meaning of: adding one octave to a simple, non-compound interval. If you need to figure out a compound perfect 5th, which is a different name for a Perfect 12th, just figure out a simple perfect 5th.
When accidentals are applied to a basic interval it either becomes larger or smaller. But the numerical classification remains the same. The use of accidentals allows for this action. There are 2 groups of intervals. Group 1 and group 2.
Group 1 includes: unison, 4th, 5th, octave.
Group 2 includes: 2nd, 3rd, 6th, 7th.
Group one intervals are named:
Perfect = P two tones that sound the same [harmonic].
Augmented = A is a term for an interval that is one half step larger than the perfect interval.
Diminished = d is a perfect interval made to be one half step smaller.
Another essential term to understand is interval inversion. An easy way to think of writing an interval inversion is this: the top note is written on octave lower on the staff and is now on the bottom, and the bottom note is also an octave lower on the staff lines, but now it is the top note. Which we call inverted.
It’s easy to figure the way to convert an original interval to an inverted interval. Perfect intervals remain perfect either way when converted. Augmented intervals change into diminished intervals. Although an augmented octave cannot be inverted. Diminished intervals invert to Augmented intervals.
Group two uses a different set of terms to show intervals. [Below]
Augmented = A, Major = M, Minor = m, Diminished = d.
To be clear, in group 2, the terms major and minor are used instead of the term perfect. It’s easy in concept to make a major interval smaller. Decrease it by one half step to accomplish this. Group two intervals can be inverted also. Major converts to minor. Minor converts to major, Diminished to Augmented. Augmented to diminished.
