Principles for part writing in root position
 When a triad is in root position double the bass
 Each chord should contain two roots, one third and one fifth
 The voices should be in normal distribution…not crossed
 The interval between adjacent upper voices should not exceed and 8ve
 Step-wise motion should predominate in leading voices from one chord to another
 Melodic leaps of an A2 or A4 should be avoided
 Consecutive P1, P4,P5, or P8 are forbidden

7. When connecting triads whose roots are a fifth (or fourth) apart, retain the common tone in the same
voice and move the remaining voices to the NEAREST chord tones to achieve correct doubling and
spacing. Write the alto and tenor voices for the second chord in each case. Retain the common tone in
the same voice

8. If, when connecting triads whose roots are a 5th (or a 4th) apart the common tone is NOT retained in
the same voice, move all voices to the NEAREST chord tones which result in correct doubling and
spacing. Write the alto and tenor voices for the second chord in each case. DO NOT retain the
common tone in the same voice.
