[Unreleased]

Fix chords so that they generate a barre and a non-barre version and prevent barre chords from picking notes before the barre.

[2.2.0]

Intervals were completely refactored according to #11 and (pedrozath#12). Thanks @art-of-dom for the valuable information. We now have new interval classes and new ways on how to deal with them. Check the wiki for more details.

[2.1.0]

Correct Flat/Sharp on Diatonic Scales
Fix chords so that they generate a barre and a non-barre version and prevent barre chords from picking notes before the barre.

Adds

Pitches and Voicings. Pitches are a way of expressing notes in a specific octave. Voicings are a way of expressing a chord with the exact pitches
Introduces a little sound synthesizer (experimental, macOS-only). Use --sound to activate it wherever the program outputs chords.
Introduces some modules classes to provide Guitar Chord finding. ColtraneInstruments::Guitar::Base.find('C6/9')
Introduces DiatonicScale and Key classes.

Changes

Guitar Chords are now outputted using the default guitar chord notation

[2.0.0]

Changes

Code has been completely refactored. Things are organized around frequencies. Intervals are backed by cents, which is an logarithmic measure used to measure the distance between 2 frequencies.

We have now a distinction between PitchClass and Note. The first is a generic concept of Notes while the latter deals with sharps and flats logic.

That refactor will allow us to in the next versions refactor scales so that they output proper sharps and flats (pedrozath#3).

[1.2.3]

Fixes

Bug in progression command

[1.2.2]

Fixes

A bug of the previous functionality that generated a infinite loop if a command wasn't found

Fixes

Fixes a bug in Piano

[1.1.2]

Fixes

Progression specs
Comments out classic progressions for now

Adds

Progression.find(*%w[AM DM F#m EM])

[1.1.0]

Changes

The qualities are now more procedural, less hardcoded as possible. The refactor has caused the chord list shorter. That may be an issue for some users, and if so, it should be addressed in next versions. However, I believe that reduces the spam, since we are focusing on the more relevant chords, as they're the basis for building more "exotic" chords.
Intervals are now registered and displayed in the english language order. Ex: Minor Third was 3m and now is m3.

Adds

A lot of helper methods for obtaining interval information! Interval has methods like #minor_third?, #major_second?, which are pretty self-explanatory. #full_name and #full_names are also added, the latter returning intervals that are pretty much the same, such as Major Second and Major Ninth. Interval sequences have methods like #has_minor_third? and #third, which will return the third it has, no matter if its major, or minor.
Roman Chords and Chord Progressions are finally here! It's a bit experimental yet, the latter definitely needs more specs.
