It is important to have a correct approach to practice. You will benefit more from several short practices (e.g., 15-30 minutes per day) than one or two long sessions per week. This is especially so in the early stages, because of the basic nature of the material being studied. In a practice session you should divide your time evenly between the study of new material and the revision of past work. It is a common mistake for semi-advanced students to practice only the pieces they can already play well. Although this is more enjoyable, it is not a very satisfactory method of practice. You should also try to correct mistakes and experiment with new ideas. It is the authors’ belief that the guidance of an experienced teacher will be an invaluable aid in your progress.
The electric organ, invented in the 1930s, gained mainstream popularity through models like the Hammond B-3 (pictured), which is used extensively in jazz, blues and rock music. The unique sound is created by "tonewheels" rotating in front of electromagnetic pickups, and the sound that this produces can be modified through several switches and drawbar combinations to create millions of different tonal variations. Many modern electric organs are digital, although they still share common design traits with original electro-mechanical organs.
