More details of this interval are at Fb-min-3rd. The note interval name for the 3rd note / scale degree is therefore minor, also called m3 for short. Now look at the complete Note interval table, and identify the note interval that has a distance of 3 half-tones (first column), and with an interval no. To identify the triad chord quality that has these notes, begin by counting the number of half-tones / semitones between the root and each of the notes.įor the 3rd Interval (note 2 on the diagram) the distance between Fb and Abb is 3 half-tones. To identify the triad chord note names, use the 1st, 3rd, and 5th columns / scale degrees, which are notes Fb, Abb, and Cb. The table below shows the Fb natural minor scale, ordered to show the 1st note as the first column in the table. This step shows how to identify the notes and the name of a triad chord whose root note is the 1st scale degree of the Fb natural minor scale. The steps below will show how this works for each triad in turn, but in practice it might just be easier to memorize the triad quality table in the Scale chord summary for each scale type. Taken together, the combination of the 3rd and 5th note intervals will define the complete triad quality name. To decide the name the chord quality, each step below will use note intervals to calculate how many half-tones / semitones / piano keys between the root and the 3rd (and 5th). Should each triad that we build be called major, minor, augmented, or diminished ? Every triad chord must have one of these quality names. This pattern is repeated for all 7 notes in the scale, resulting in 7 triad chords.Īlthough the above method identifies each triads notes from the scale used - it does not identify the complete chord name including its quality. the 1st, 3rd and 5th positions relative to that 2nd root note. The second triad below will repeat this, but this time starting on the 2nd note, so its notes will be Gb, Bbb and Dbb - ie. Triad chords are built using the 1st, 3rdand 5th notes of the scale, so the first triad below will constructed a chord using notes Fb, Abb and Cb. The triad chord will be built using only the notes of the scale we are interested in. Starting from the 1st scale note, each lesson step below will take each note in turn and construct a triad chord using that note as the root / starting note of that chord. The piano keyboard below contains the notes of the Fb natural minor scale.

This step shows the scale note names that will be used to construct all triad chords that harmonize with those scale notes.
