![]() Why hard B became the norm in some countries and soft B the norm in others is still an unexplained mystery, but might say something about how often B was performed flat or sharp in various countries. To put this in context, let’s play the C an octave higher. ![]() In an earlier article I showed you that all you had to do to find the dominant 7th of any chord is to find the note that is a whole step below the root. So the 1, 3, and 5 in the C major scale is C-E-G. Now the major chord formula is the root or first note, third, and fifth. Even if you don’t have your Circle of Fifths that formula will help find all major scales. The need for a third form, # (derived from the natural sign) only came later as notes could be seen as needing three different forms. First we have to add the dominant 7th that this 9th chord implies. All major scales have the formula W-W-H-W-W-W-H, the H being a semitone and the W two semitones or a whole tone. Later, as RedGrittyBrick said, the soft b form was used to indicate any note which was a half-step above the note below it and hard b form for any note a whole step above the note below it (for instance F# would be written as F-natural, while an F-natural following F-sharp would be written as F-flat). then select chord type (quality) from the list below. As written in the earliest sources, hard B looked a bit like an H with an added crossbar which may have been the reason for the change to H (or it was the next letter of the alphabet both theories have manuscript support). In the late medieval system there were six normal notes, C D E F G A, and one note that had two forms, soft B (b) which was a semitone above A and hard B (♮) which was a whole tone above A. This free piano chord finder helps you identify chords by only supplying the note values.
