|Part Writing Tips||Theory Things William Wieland|
Many begin by first writing the bass and soprano. When writing|
alto and tenor parts, consider working backwards from cadences.
Work in the following order:|
1. Correct Chords — Write chords in simple position on a separate staff if necessary.
2. Bass Line — Consider the roman numerals and the inversion.
3. Reasonable Ranges
• Soprano and Bass on the staff
• Tenor may sing above middle C
• Alto may sing below middle C
4. Sonorous Spacing
• Only the bass can be more than an octave from the next part.
• Check the alto and tenor lines. Perhaps exchange them.
5. Nearest Notes
• The nearest note of all is not moving. Can any voices remain on the same pitch?
• Conjunct motion is the smoothest. Can any voices move by step?
• Resolve tendency tones properly in Dominant Function Chords.
6. NO Perfect Parallels
• Unisons, Octaves or Fifths
• If 2 parts move in parallel, check for perfect intervals.
• If the bass moves by step, move the other parts in the opposite direction.
7. NO Doubled Active Tones — Accidentals, ti, and 7ths of 7th chords
