Class one of this series concentrates on the basics of the diminished scale, how and when to use it, and how to weave it organically into single-note improvisations.

The diminished scale is a musical structure that was used extensively in early twentieth-century classical music in the works of such composers as Stravinsky, Debussy, Ravel, Scriabin, and Bartok.  Jazz musicians eventually began to use the scale as well, to the extent that it has become a staple of the modern jazz musician’s vocabulary.  Despite how common this sound has become, it is frequently misunderstood and not studied as thoroughly as other often-used structures like the major, harmonic minor, and melodic minor scales.

This three-part series of classes will attempt to remedy this situation by exploring in systematic detail the use of the diminished scale for melodic improvisation and by finding all of the three- and four-note structures available in the scale.  We will discuss the use of these structures as chords for comping and for harmonized melodies as well as arpeggios for single-note playing, and all will be broken down in a logical and guitar-friendly manner.

Although the diminished scale in and of itself may not necessarily be a “modern” sound in jazz, many in the modern school of jazz guitarists like Kurt Rosenwinkel, Jonathan Kreisberg, and Mike Moreno have begun to use diminished sounds in new and exciting ways in their playing and original compositions.

This series explains and implements the traditional uses of the diminished scale, but many of the sounds go beyond the typical and into uncharted territory.  And though this class provides numerous examples of interesting ways to make use of these sounds, the material presented here could easily be a springboard for each individual to forge a unique and personal vocabulary.

This series could be helpful to jazz guitarists of any level (or any musician who wants to learn more about the diminished scale), but it is mainly geared toward intermediate to advanced players who already have command of some of the fundamentals of guitar playing and of the jazz language.

  1. A course you can return to many, many times


    I have purchased many of Tom’s classes and have been very happy with all of them. It is amazing how much material he can put into one class. And he does it in such an organized way that you can keep going back to different sections to improve or brush up on one particular aspect of the material without having to go looking all over the lesson to find what you need. I particularly like the scale exercises that help you resolve from the diminished scale to a major scale – this is something I have REALLY needed to work on in my own practice (that is, connecting ideas). If you really want to improve your command of a particular concept then you will be very happy with all of Tom’s classes (check out his melodic minor series as well for a similar approach).

    Tom’s classes are the best instructional videos on the net. Consistently outstanding instruction from a monster player. Buy all his videos without fear… these videos will provide a lifetime of inspiration.

    This whole series on the Diminished scale is fantastic! Tom is a master teacher. He has a way of making everything very easy to understand, even when dealing with complex subjects. He gives plenty of examples which are by themselves excellent means to digest the material, while on the other hand it’s easy to figure out new ways for practicing these exercises, in order to personalize them according to your own level and interests. I own several of Lippincott’s videos and they all have the same level of excellence.
    I am a practicing musician and a college professor, and these teachings serve me well in both areas. I find it easy to know how to apply these concepts to my own playing (I’ve been playing for almost 30 years), but I also easily adapt the same concepts to teach my beginner/intermediate students. The method of organization has helped me in organizing my lessons better.
    I could not be happier with these courses!
    These videos are worth so much more than the price you pay for them.

    As always another great class from Tom. You will get the basics about the diminished scale, examples and ways to use in real context, everything well organized. Also don?t forget to check the diminished classes 2 and 3. You will get a lot information that you wont find on the internet or any other book.

    Like Tom’s previous lessons, I’ve found all three of his latest lessons based on the Diminished scale to be excellent value. He presents the material in a very comprehensive and clear manner. I have never been disappointed with any of his lessons.

    Highly recommended

    Thanks again Tom and Mike.

    All Tom’s classes are top notch and this one is no different. He is a gifted teacher that offers a vast amount of material. My suggestion is to watch his lessons once through without your guitar and just enjoy and absorb the material. Then go back and watch it in chucks while practicing along with the material. I’ve been through this course three times now and am still learning.
