How to Construct an A Flat Minor Triad in Music Theory

In music theory, a triad refers to any chord consisting of three pitches that can be stacked either vertically or horizontally. These types of chords are the building blocks for more complex harmonies and melodies within music compositions.

To construct a minor triad specifically, we need to focus on scale degrees 1, 3, and 5 from the natural minor scale. This article will walk you through these steps using the key of A flat as an example.

Step 1: Understand Scale Degrees in Natural Minor Scales

Before diving into constructing our specific chord progression, let's quickly review what we mean by 'scale degrees' within music theory context:

- Scale degree one (or root) is always represented by its letter name without any flats or sharps.

- The third scale degree can be either a major or minor third depending on the type of triad being formed.

For our example, let's say we're working with an A flat natural minor scale. Therefore:

* Scale degree 1 (or root) would simply be 'A'

* Scale degrees 3 and 5 would then correspond to 'C' and 'G,' respectively.

Step 2: Apply These Concepts to Construct the Minor Triad

Now that we have our individual pitches identified, let's apply them together in order to construct an A flat minor triad:

1. Start with scale degree one (A) as your tonic note.

2. Next, add a perfect fifth above it - which would be G# or B natural depending on the key signature but since this example is using A flat major/mixolydian mode; so we'll call it just 'G'.

3 Finally, take another step down from there and you've got your flattened third: E.

So altogether when played together in any order as follows:

A - G - E

You will have yourself a fully functional minor triad using the notes A flat major scale!
