Are you interested by studying extra approximately track yet have came upon so much fabric condescending or to give issues magically rather than logically? the good news is that a lot of song could be understood with programming and math, issues you're already sturdy at! during this e-book you'll examine a few components of tune from a programmer's standpoint. You'll know about the primitives of track resembling notes and period, the technique of combining these primitives into causes and chords, operations comparable to transposition, retrograde, and inversion, and the technique of abstraction (phrases and shape) utilizing Python and a few simple arithmetic. each proposal during this ebook is defined in English with a corresponding implementation in Python, utilizing the Pyknon song library.
