THE 12 SEMITONES OF PITCHED MUSIC


                  Between  the seven musical  alphabet  notes,  there are semitones  (half  steps).  Western music
                  consists of 12 semitoneswithin an octave.
                  Notes on a Piano/Keyboard

                  On a piano keyboard:

                      White keys represent the natural notes (A, B, C, D, E, F, G).

                      Black keys represent sharp (#) and flat (♭) notes.
                      Moving one key to the right (black or white) is a semitone.

                  The 12 Notes in an Octave:

                  A, A#/B♭, B, C, C#/D♭, D, D#/E♭, E, F, F#/G♭, G, G#/A♭
                  Activity: Identify Notes on BandLab

                      Open BandLab and select the piano instrument.

                      Identify each note on the virtual keyboard.
                      Play a chromatic scale (all 12 semitones in sequence).




                            NOTE INTERVALS

                  An interval is the distance between two notes.

                      Whole step (tone) = Two semitones apart.

                      Half step (semitone) = One semitone apart.
                  Common Intervals:

                      Unison (same note)

                      Minor second (1 semitone)

                      Major second (2 semitones)
                      Minor third (3 semitones)

                      Major third (4 semitones)

                      Perfect fourth (5 semitones)
                      Perfect fifth (7 semitones)
