HALF STEP

A "Half Step" refers to moving 1 musical step down or up the musical chromatic scale.  We may normally think in terms of a full step within a key.  Let us look at scales.  We will use a scale in the key of C.

Scale in Key of C

Notes C D E F G A B C D E F G A B C    
Number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15    

A scale in the key of C shown above are the normal notes that one might expect in a song.  Instead of calling the notes C, D, E, etc.  or 1, 2, 3 , we also could think of the sequence as the singing notes: do, re, me fa, so, la ti do.

Chromatic Scale starting with C

Notes C C# D Eb E F F# G G# A Bb B C C# D    
Number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15    

A chromatic scale is all of the possible musical notes - and not just the notes in the C scale.  Note that between two "whole steps" such as C to D, that there is a "half step" in between, that we could call C# (C sharp) or we could also call Db (D flat).  Note that C# and Db are the same note, and could be called by either name.  Basically, one half step down from D is the same as one half step up from C.

In this case, a Half Step is movement one position in the chromatic scale - and not the scale in a given key.  For example.  One half step above F is F# (or Gb).  One half step below B is Bb (or A#).
