Installation

You need a working Haskell installation (GHC + base, stack/cabal).

1. scalez uses sox for audio playback. So you have to install it:

   • OSX
     • $ brew install sox
   • Ubuntu
     • $ apt install sox
   • Arch
     • $ pacman -S sox

2. Install the process haskell package:

   • cabal update && cabal install process

3. Clone this repo, compile and move scalez to your executables:

   $ git clone https://github.com/nkleemann/scalez
   $ cd scalez
   $ ghc -o scalez Main.hs
   $ cp scalez /usr/local/bin/scalez
   

Usage

$ scalez <rootnote> <scalename> [--sing]

All notes are represented as lower- or uppercase letters. Black keys are represented with sharps:

C C# D D# E F F# G G# A A# B

You can find the list of all available scales by invoking: scalez --list. The name you pass has to match - ignoring upper or lower case inputs.

If you want to listen to a specific scale you pass the --sing flag at the end.

Contributing

You can add a new scale by adding it to the scalez Map in Scale.hs. A Scale is modelled after a fixed sequence of intervals/steps.

Notes

This is a WIP - I will extend the functionallity, clean up the architecture and install process and handle audio playback in a better way. Functionallity is verified under osx and gnu/linux.
