Jazz has long been considered to be one of the most demanding forms of contemporary music to master. So much so, that many would be Jazz musicians will spend years learning music theory, alongside developing advanced playing techniques, simply to get a start in this fascinating musical genre.

The major difference between Jazz and most other forms of music is in the fact that improvisation is not only encouraged, it forms the very backbone of the style. Although there are many Jazz classics, no two musicians or bands will play these songs the same. They will follow the basic progression, but will be given a new inflection through personal and group improvisation.

The ability to play improvisations relies heavily upon two things; first the musicians creativity, and secondly upon the musicians knowledge of musical theory. Of course, there are many fine Jazz players out there who will tell you that they do not know any music theory. The simple truth of the matter is that they do, they just do not know it. They have spent years learning to play by ear, and although they cannot name the correct musical terms for what they do when they are playing, they are clearly demonstrating a deep knowledge of music theory at a base level.

For those wishing to take up playing Jazz, then a firm grounding in music theory is entirely recommended. Even the rhythm section of a Jazz band is encouraged to improvise and embellish the piece being played. Rhythm guitar players will be called upon to construct complex chord patterns, including augmented, diminished, 5th, 9th and 13th chords. They will also be expected to follow the soloist, should they decide to shift tempo, key or mode.

As a soloist, playing Jazz is all about creativity, backup up by an understanding of what they are doing musically. Many Jazz musicians, when questioned about scales, will smile and reply, “What is a scale? I don’t know any!” This is something of an insider’s Jazz joke, as most Jazz soloists play what they feel, not what they know works mathematically. Of course, this is far from the truth, but a Jazz player will have transcended standard scales in many ways. Instead, using their ear, they will be able to find step off points, into new scales and modes, shifting the music as they go. This of course, requires an immense amount of theoretical knowledge, either learned conventionally, or learned over years of playing by ear.

Playing Jazz can be one of the most rewarding experiences any guitar player is likely to experience. A good Jazz performance will see the musician develop ideas, and musical concepts on the fly, breathing fresh life into Jazz classics, while enthralling the audience like a true virtuoso. Although a thorough understanding of music theory is not a prerequisite for becoming a competent Jazz player, it can be seen as an effective short cut, removing the requirement to play Jazz for decades before becoming entirely competent in its application.
