If you’re a music enthusiast, you may have come across the term “II06” in your studies or discussions with other musicians. But what exactly does it mean in music theory?

II06 is a chord symbol that represents a specific chord in music theory. It’s made up of Roman numerals and other symbols that indicate the chord’s qualities and function within a key.

To understand what II06 means, we need to break down each component of the symbol. The first part, “II,” represents the chord’s position within the key.

In Roman numeral notation, uppercase Roman numerals represent major chords, while lowercase Roman numerals represent minor chords. In this case, “II” indicates a minor second chord.

The next part of the symbol is “0,” which indicates that the chord is in root position. This means that the root note of the chord is in the bass or lowest voice.

Finally, “6” indicates that the third of the chord is in the bass. This is known as a first inversion chord.

So when we put all these parts together, II06 represents a minor second chord in root position with its third note in the bass.

Now that we know what II06 means, let’s explore its musical function within a key. In most cases, II06 functions as a secondary dominant to V or V7 chords. This means that it creates tension and leads to the dominant chord by borrowing notes from outside of the key.

For example, let’s say we’re in C major and we want to use II06 to lead into V7 (G7). The II06 chord would be D-F-A-C (Dm6), which contains an F natural instead of F# found in C major scale. This note acts as an altered leading tone to G (the fifth of Dm6), creating tension and resolving to G7 (G-B-D-F).

In conclusion, II06 is a chord symbol that represents a minor second chord in root position with its third note in the bass. It functions as a secondary dominant chord that leads to V or V7 chords by borrowing notes from outside of the key. Understanding this chord and its function can enhance your music theory knowledge and songwriting skills.
