d'accord

d'accord is a focused JavaScript module designed for parsing complex music chord symbols, encompassing both Jazz and Classical notation standards. It accurately interprets a wide range of chords, from basic power chords like 'D#5' to sophisticated real book entries such as 'G7#5' and 'Dm7b5', or even intricate structures like 'Fsus4maj#11' or 'Cm13b5#9'. Crucially, d'accord only parses the chord suffix (the part without the root note) and returns an array of relative intervals (e.g., ['P1', 'm3', 'd5', 'm7']) rather than absolute notes. This design makes it a versatile tool for music theory applications, often used in conjunction with libraries like Teoria to construct full chords from a specified root note. The current stable version is 2.0.1. Release cadence is not explicitly stated but implies a steady maintenance, with major version updates indicating significant changes. Its key differentiator is its robust and forgiving parsing logic for a vast array of chord suffixes, specifically designed to output relative intervals for maximal flexibility in musical analysis and composition.
