keyboardLayouts.js

// ANSI layout is assumed (and this won't make sense otherwise).
// Descriptions of the layouts below use terms like columns and rows.  A column
// would refer to the collection of keys "zaq1" (column 1) or "xsw2" (column
// 2).  A row would refer to the collection of keys "zxcvbnm,/" Ascending a
// column would mean moving from "z" to "a" to "q" (away from your chest) and
// descending is the inverted direction.  Likewise, ascending a row would mean
// moving from "z" to "x" to "c" to "v" and descending the inversion as well.

// melodic layout
// columns ascending in perfect 4ths
// rows ascending in major 2nds
//
// This an oddly useful layout, optimized for melodic playing.  The major
// scale modes are very easily accessible (as well as chromatic should you
// desire).  Perfect fifths are a comfortable keypress away.
