Algorithmic composition is a method of creating music using algorithms, which are step-by-step procedures or formulas. This approach can involve mathematical models, computer programs, or rules that generate musical notes, rhythms, and structures. By using algorithms, composers can explore new musical ideas and patterns that might not be easily conceived through traditional methods. This technique has roots in various fields, including mathematics and computer science, and has been utilized by composers like Iannis Xenakis and Brian Eno. Algorithmic composition can produce unique and complex pieces, allowing for a blend of creativity and technology in the music-making process.
