In BACH CHORALE
1. Bach’s mostly used cadences include perfect (V-I) and imperfect (ending on V) cadences Reference: https://www.cmburridge.com/teaching/bach-chorales/lesson-5-perfect-cadence-fingerprints/ https://www.cmburridge.com/teaching/bach-chorales/lesson-6-imperfect-cadence-fingerprints/ 2. Bach rarely writes parallel/consecutive fifths and octaves Reference: https://www.cmburridge.com/teaching/bach-chorales/lesson-2-rules-of-chorale-harmony/ 3. Following the second point, the consecutive written by Bach are categorized as ‘Fermata’ consecutive, non-structural consecutive, and structural consecutive. Reference: https://www.bachchorales.com/ConsecutivesInChorales.htm 4. Usually ends with leading note on the tonic chord. Mustn’t resolve the leading note on the third. Reference: https://www.choraleguide.com/vl-leadingnotes.php 5. Bach constantly doubles the thirds. Although textbooks don’t recommend to do this. The thirds are the third of the chords. Reference: http://www.russellsteinberg.com/blog/2013/9/26/ac8tzs1vmjs2n45y5o7jmc83gwvd7s 6. succession to the first point. Bach frequently cross voices, but the textbook doesn’t recommend people to do that. Cross voices mean SATB part sometimes cross with each other, exchanging notes. Reference: http://www.choraleguide.com/vl-spacing.php 7. Bach uses chromaticism (think extra sharps and flats) to such an extent that powerful dissonance threatens to obliterate the clarity of the simple chorale tunes. Chromaticism is the use of notes foreign to the mode or diatonic scale upon which a composition is based. Chromatic tones in Western art music are the notes in a composition that are outside the seven-note diatonic (i.e., major and minor) scales and modes. On the piano keyboard, the black keys represent the 5 chromatic tones that do not belong to the diatonic scale of C major; black and white keys together add up to the chromatic scale of 12 tones per octave. Reference https://www.britannica.com/art/chromaticism 8. Leading notes that rise to the 3rd or fall to the 5th of chord I on the fermata chord. Leading note (or tone) refers to the 7th note in the major scale. It's always one semitone below the root, which gives its name to the key. So, in key C, that note's B. Resolution is 'coming home comfortably'. It rises to the fermata and rise into the 3th or 5th.
