+# Scale Generator
+
+Given a tonic, or starting note, and a set of intervals, generate
+the musical scale starting with the tonic and following the
+specified interval pattern.
+
+Scales in Western music are based on the chromatic (12-note) scale. This
+scale can be expressed as the following group of pitches:
+
+A, A#, B, C, C#, D, D#, E, F, F#, G, G#
+
+A given sharp note (indicated by a #) can also be expressed as the flat
+of the note above it (indicated by a b) so the chromatic scale can also be
+written like this:
+
+A, Bb, B, C, Db, D, Eb, E, F, Gb, G, Ab
+
+The major and minor scale and modes are subsets of this twelve-pitch
+collection. They have seven pitches, and are called diatonic scales.
+The collection of notes in these scales is written with either sharps or
+flats, depending on the tonic. Here is a list of which are which:
+
+No Sharps or Flats:
+C major
+a minor
+
+Use Sharps:
+G, D, A, E, B, F# major
+e, b, f#, c#, g#, d# minor
+
+Use Flats:
+F, Bb, Eb, Ab, Db, Gb major
+d, g, c, f, bb, eb minor
+
+The diatonic scales, and all other scales that derive from the
+chromatic scale, are built upon intervals. An interval is the space
+between two pitches.
+
+The simplest interval is between two adjacent notes, and is called a
+"half step", or "minor second" (sometimes written as a lower-case "m").
+The interval between two notes that have an interceding note is called
+a "whole step" or "major second" (written as an upper-case "M"). The
+diatonic scales are built using only these two intervals between
+adjacent notes.
+
+Non-diatonic scales can contain other intervals.  An "augmented first"
+interval, written "A", has two interceding notes (e.g., from A to C or
+Db to E). There are also smaller and larger intervals, but they will not
+figure into this exercise.
+
+## Setup
+
+Go through the setup instructions for Javascript to install the necessary
+dependencies:
+
+[https://exercism.io/tracks/javascript/installation](https://exercism.io/tracks/javascript/installation)
+
+## Requirements
+
+Install assignment dependencies:
+
+```bash
+$ npm install
+```
+
+## Making the test suite pass
+
+Execute the tests with:
+
+```bash
+$ npm test
+```
+
+In the test suites all tests but the first have been skipped.
+
+Once you get a test passing, you can enable the next one by changing `xtest` to
+`test`.
+
+## Submitting Incomplete Solutions
+
+It's possible to submit an incomplete solution so you can see how others have
+completed the exercise.
