Music for Geeks and Nerds
Are you curious about studying extra approximately tune yet have chanced on such a lot fabric condescending or to provide issues magically rather than logically? the good news is that a lot of tune may be understood with programming and math, issues you are already strong at! during this ebook you are going to study a few components of tune from a programmer's viewpoint. you are going to find out about the primitives of tune similar to notes and period, the technique of combining these primitives into factors and chords, operations similar to transposition, retrograde, and inversion, and the technique of abstraction (phrases and shape) utilizing Python and a few simple math. each inspiration during this booklet is defined in English with a corresponding implementation in Python, utilizing the Pyknon tune library.
aren't producing the subject matter (the complete topic is encoded within the ﬁle canon-crab). whereas this is often real, the compositional method is absolutely defined within the code above. If we alter the subject and run the code we’ll get a diﬀerent composition with an identical procedure. in truth, you'll alternative canon-crab along with your personal ﬁle. workout eleven.

Straus’ advent to Post-Tonal eory is an effective booklet. additionally, Benson’s track: a Mathematical Oﬀering is freely to be had. • while you're drawn to programming, try out Python libraries seventy four.
leisure is a very easy type. It has just one characteristic: dur the length worth as ﬂoat element (quarter is 0.25 due to the fact that 1/4 = 0.25). And it has just one approach: stretch_dur(factor ) Multiplies the length by means of issue and returns a brand new leisure with the ensuing length. 4.2 notice e type word has six attributes and accepts the next attributes as key-phrase arguments: worth, octave, dur, and quantity. price the integer price for a be aware, from zero to eleven. octave the octave worth the place the vital octave.
Notes (to continue issues short). if you'd like a extra descriptive identify, you should use the verbose estate: 4.2. notice 33 Music for Geeks and Nerds >>> >>> >>> >>> >>> >>> >>> >>> >>> >>> Note(2)
Retrograde() Returns a brand new NoteSeq with the order of things reversed. transposition(index) Returns a brand new NoteSeq with the notes transposed via a transposi- tion index, within which the index is an integer. It’ll transpose purely the notes and go away the rests untouched. >>> >>> >>> >>> a = NoteSeq(”C4 D8 R E”)
