Download or read book Fundamentals of Guitar written by MILES OKAZAKI and published by Mel Bay Publications. This book was released on 2015-02-25 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to be useful for guitarists at any skill level. Beginners can use it as an introduction to the foundational concepts of the instrument, intermediate players can use it for training and theoretical work, and advanced players can explore the sections on advanced theory, extended technique andthe exhaustive tables of melodic and rhythmic possibilities.It is divided into two parts: pitch and rhythm. Part 1 (pitch) begins with the properties of string, harmonics, and tuning systems. It then moves methodically through pitch information, beginning with locating all versions of a single pitch, building pentatonic, heptatonic, and all possible symmetrical scales. This is followed by a study of intervals, with all possible locations of every two pitches, and a long study that moves through every possible fingering of three pitches, with a series of exercises to master triadic syntax. Part 1 closes with a study of four-pitch structures and complete tables that show all possible pitch sets in circular visual notation.Part 2 (rhythm) begins with a complete course in "Symmetrical Picking," a methodbased on drum rudiments that builds control in the picking hand through an exhaustive variety of movements. The focus of this section is building a strong rhythmic foundation, with a focus on efficiency, accuracy, speed, dynamics, and groove. It is followed by a study of legato playing, working with ornaments and slides. The study of playing with fingers on multiple strings takes up the remainder of the book. This begins with the study of pulse against pulse, playing twosimultaneous tempos. The book concludes with a study of polyrhythm, playingone rhythm against another. Plain English is used as much as possible to describe theoretical concepts, and hundreds of illustrations were made for the book as an aid to those who either don't speak English or prefer to think visually. This approach is designed to beinclusive and to promote creative practice. The main idea of the book is described in this passage (page 154): "Even in this small area there is a lot of material, potentially a lifetime of study. The amount of information can feel overwhelming to students at any level. For this reason, the book is designed for self-directed practice, with an emphasis on what the player "could" do, rather than what the player "should" do. The principle is to develop your own learning process, rather than following someone else?s. The ability to make choices is essential in finding a personal approach to the instrument. Pick and choose the studies that seem interesting - there should be enough variety to accommodate a wide range of personalities. If any particular concept or exercise has been useful as the starting point for a new creative direction, then the book has done its job. Its purpose is not to push any dogma,method, or style, but to open the door to options for guitarists of any background that are looking for new perspectives.

Download or read book Hyperspherical Harmonics And Their Physical Applications written by Avery James Emil and published by World Scientific. This book was released on 2017-11-27 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyperspherical harmonics are extremely useful in nuclear physics and reactive scattering theory. However, their use has been confined to specialists with very strong backgrounds in mathematics. This book aims to change the theory of hyperspherical harmonics from an esoteric field, mastered by specialists, into an easily-used tool with a place in the working kit of all theoretical physicists, theoretical chemists and mathematicians. The theory presented here is accessible without the knowledge of Lie-groups and representation theory, and can be understood with an ordinary knowledge of calculus. The book is accompanied by programs and exercises designed for teaching and practical use.

Download or read book Harmonics in Offshore Wind Power Plants written by Jakob Bærholm Glasdam and published by Springer. This book was released on 2015-10-26 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on cutting-edge findings regarding harmonic stability assessment for offshore wind power plants (OWPPs). It presents a timely investigation of the harmonic stability interaction between OWPPs on the one hand, and associated control systems in the wind turbines and other power electronic devices in the transmission system on the other. The book particularly focuses on voltage-sourced converter high-voltage direct current (VSC-HVDC) and static compensator (STATCOM) systems. From a practical perspective, the book reports on appropriate models for power electronic devices. It describes how the frequency domain evaluation approach can be assessed by comparing results obtained with the Nyquist stability criterion against the more detailed electromagnetic transient based model realized in the PSCAD/EMTDC simulation program. The book also provides a concise yet complete overview of large OWPPs that incorporate power electronic devices on a broad scale, and highlights selected challenges and opportunities in the context of real-world applications.

Download or read book Approximation Theory and Harmonic Analysis on Spheres and Balls written by Feng Dai and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph records progress in approximation theory and harmonic analysis on balls and spheres, and presents contemporary material that will be useful to analysts in this area. While the first part of the book contains mainstream material on the subject, the second and the third parts deal with more specialized topics, such as analysis in weight spaces with reflection invariant weight functions, and analysis on balls and simplexes. The last part of the book features several applications, including cubature formulas, distribution of points on the sphere, and the reconstruction algorithm in computerized tomography. This book is directed at researchers and advanced graduate students in analysis. Mathematicians who are familiar with Fourier analysis and harmonic analysis will understand many of the concepts that appear in this manuscript: spherical harmonics, the Hardy-Littlewood maximal function, the Marcinkiewicz multiplier theorem, the Riesz transform, and doubling weights are all familiar tools to researchers in this area.

Download or read book n Harmonic Mappings between Annuli written by Tadeusz Iwaniec and published by American Mathematical Soc.. This book was released on 2012 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iwaniec and Onninen (both mathematics, Syracuse U., US) address concrete questions regarding energy minimal deformations of annuli in Rn. One novelty of their approach is that they allow the mappings to slip freely along the boundaries of the domains, where it is most difficult to establish the existence, uniqueness, and invertibility properties of the extremal mappings. At the core of the matter, they say, is the underlying concept of free Lagrangians. After an introduction, they cover in turn principal radial n-harmonics, and the n-harmonic energy. There is no index. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com).

Download or read book Harmonic Experience written by W. A. Mathieu and published by Simon and Schuster. This book was released on 1997-08-01 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of musical harmony from its ancient fundamentals to its most complex modern progressions, addressing how and why it resonates emotionally and spiritually in the individual. W. A. Mathieu, an accomplished author and recording artist, presents a way of learning music that reconnects modern-day musicians with the source from which music was originally generated. As the author states, "The rules of music--including counterpoint and harmony--were not formed in our brains but in the resonance chambers of our bodies." His theory of music reconciles the ancient harmonic system of just intonation with the modern system of twelve-tone temperament. Saying that the way we think music is far from the way we do music, Mathieu explains why certain combinations of sounds are experienced by the listener as harmonious. His prose often resembles the rhythms and cadences of music itself, and his many musical examples allow readers to discover their own musical responses.
