When first learning to play a musical instrument, scale key signatures can appear very confusing but Scale Logic helps to illustrate that this is not the case.  This unique app gives you an alternative and fresh approach to learning major and minor scales based around the tones and semitones found within a scale.

Within a major and minor scale, the pattern of tones and semitones (the musical intervals) are fixed from the starting note to the end note.  This fixed pattern can be applied to any starting note to demonstrate how a scale is constructed.  Using this fixed pattern and while looking at piano keys, you can see how a scale's key signature is derived.  For example, by placing the fixed pattern of musical intervals at the starting note of the G major scale (note G) you would play a series of white notes until you reached he black note of F#.  Therefore the key signature of G major is F#.

This fixed pattern shows you which notes must be played to make a scale and the sharps/flats which give the scale its identity.
