Dynamics is one of the most important tasks of the conductor. Each phrase requires own dynamics, clarity of reproduction. Most are in parallel with dynamics and tone height. If the melody rises, strengthening the tones and conversely. Basic knowledge about the dynamics: with the larger gesture comes the greater power of sound (with typical movements, face mimicry, motivation face to face for singers). For dynamics apply the principles of tectonics - a dynamic hierarchy, every song should have only one dynamic peak.
