The terms we use to describe chords, major, minor, dominant, diminished, etc., are often called the quality of a chord. As music stuudents we learn the official, theoritical, cut and dried definition of chord quality which refers to the construction of the chord, or the intervals (distances) between its notes. As a performing musician and an improvisational artist chord quality means something quite different to you: its the generall overall flavor, the musical effect and the artistic impact of the chord that is important. For the modern, working musician the three types of chord qualities that are iimportant to you are: major, minor and dominant 7.
As I have said before, in order to learn lead guitar you must play lead guitar. This statement may seem a bit paradoxical but it is entirely true. It means that you are your own best teacher, best critic and best audience and as you develop your own cool and interesting vocabulary you are taking mental notes along the way remembering what works for you and what doesn’t. Imagine yourself playing with the best band in town, being there lead player and adding new unique and original ideas to the performance. Pretending.
The exercise below is a generic pop/ rock groove centered on an A bass note -since I am only using the root note the music will accept either a major, minor or dominant chord sound as a basis for your soloing. As you are practicing with the track focus on only one chord at a time, do not change chord sounds in the middle of the track. At first, use only the tools and techniques that we have learned in the course so far: chord tones and single chromatic approach notes, chord tones and double chromatic approach notes and of course the magic formula: TR3.
Throughout this entire curriculum you have learned to think of each chord you are presented with as having two, common knowledge and first choice versions: one of the first choice versions has its root note on string six the other has its root note on string five. In our world, this is called root 6 and root 5 thinking. Continuing with that line of thought, when you are presented with an A major, A minor, or an A dominant seventh chord you need to be able to play, name and find anyone of the six chords illustrated in the diagram below an effortless, automatic and instant manner.
As modern guitarists the system of music we adhere to is called tonal music, meaning that musical compositions are organized around a central note called the tonic or the I. Tonality is closely related to the concept of key and the two terms are often used interchangeably. It is generally understood that tonality refers to compositions based on either a major or minor scale, if you have studied music before, you have heard this referred to as diatonic tonality, harmonic tonality, functional tonality or common practice tonality.
For our purposes of studying lead guitar playing we are going to start by thinking of tonality as either a major key, a minor key or a dominant one based on the mixolydian mode. Every key has a scale associated with it and it is this scale, along with its harmonies, that provides the musical material necessary to compose in that key. The type of scale also provises the general overall flavor, personality and character to a musical composition or section: the tonality. The three tonalites we are concentrating on are presented below in the key of C as a graphic organizer.
The concept of tonality is similar to that of chord quality because we are continuing to study the general overall mood, flavor and artistic qualities of a complete song or section of a song. The chief difference then is that when we think about chord quality we are discussing one single chord, when we discuss tonality we are talking about a series of chords, a chord progression, an entire song or a section of a song. When expanding our discussion of chord quality to one involving tonality, the rules of the game don’t change: the major tonality, just like the major chord quality is happy and bright. The minor tonality, like the minor chord quality is dark and gloomy. The dominant seven or mixolydian tonality, is funky and bluesy just like the dominant seventh chord quality.
