How to form dominant 7th and half diminished 7th piano chords

Piano Chords...Dominant 7th and Half Diminished 7th Chords

Dominant 7th piano chords are constructed by combining the 1st, 3rd, 5th, and b7th tones of a major scale. The symbol b7th means "flatted 7th" so you would lower the 7th tone (note) of the major scale a half step. This would make the interval combination root (1st), major third (3rd), perfect fifth (5th), and minor seventh (b7th).

So to form a C dominant 7th we would use the scale tones C, E, G, and A#/Bb. The symbols for a dominant 7th piano chord are 7, Dominant 7, or Dominant seventh.

This means that, with the exception of the root (1st) tone all other tones (notes) are lowered a half step.You have learned from previous studies that a "b" preceeding a tone (note) means you lower thatparticular note (C,D, Eb, etc) a half step. This makes the interval combination a root (1st), minor third (b3rd), diminished fifth (b5th), and minor seventh (b7th). A diminished fifth is a new term in our studies and is the name given to a perfect tone (note) which is lowered ahalf step.
