As you have found out, a minor chord is made of 3 notes: the root, the small 3rd, and the 5th. The notes in a C# small triad are C#, E, and G # (Example 1). In a reduced chord, the first 2 notes are the same, but the 5th is flatted, in this case G natural (Example 2).
Example 3 demonstrates how to change from C# m to C# dim with four-note voicings on strings 2– 5 in fourth position. For three-note variations on strings 1– 3, attempt Example 4. In Example 5, these 2 voicings are shown higher up the neck, on strings 2– 4. Example 6 remains in the very same area, however on the leading 3 strings. End with a pair of voicings, as shown in Example 7, that will be simpler to play on a 14-fret guitar than a 12-fret.
You should now know numerous ways to alter from C# minor to C# reduced. A fine example of a tune that utilizes C# dim is “Only Ones Who Know” by Arctic Monkeys. In the next lesson, we’ll shift to augmented chords.
