With longer sentences, it is not easy to let the voice descend throughout; it would get uncomfortably low if there were many stresses. To avoid this difficulty, and in general the monotony of a continuous descent, it is normal to raise the voice a little at any convenient stressed syllable and continue the descent from a new high tone. Syllables thus raised in pitch are given rather more importance thereby, an effect which produces a more lively impression than the same sentence spoken as a continuous descent.
