The most fundamental principle of time beating, and the one concerning which the young conductor is apt to be most ignorant, is the following: The baton must not usually come to a standstill at the points marking the beats, neither must it move in a straight line from one point to another, except in the case of the down beat; for it is the free and varying movement of the baton between any two beats that gives the singers or players their cue as to where the second of the two is to come. We may go further and say that the preliminary movement made before the baton arrives at what might be termed the "bottom" of the beat is actually more important than the "bottom" of the beat itself. When the baton is brought down for the first beat of the measure, the muscles contract until the imaginary point which the baton is to strike has been reached, relaxing while the hand moves on to the next point (i.e., the second beat) gradually contracting again as this point is reached, and relaxing immediately afterward as the hand moves on to the third beat. In the diagrams of baton movements given on preceding pages, the accumulating force of muscular contraction is shown by the gradually increasing thickness of the line, proceeding from the initial part of the stroke to its culmination; while the light curved line immediately following this culmination indicates the so-called "back-stroke," the muscular relaxation. It is easy to see that this muscular contraction is what gives the beat its definiteness, its "bottom," while the relaxation is what gives the effect of continuity or flow. It will be noticed that when the baton is brought down on an accented beat, the beginning of the back-stroke is felt by the conductor as a sort of "rebound" of the baton from the bottom of the beat, and this sensation of rebounding helps greatly in giving "point" to these accented beats.
In order to understand fully the principle that we have just been discussing, it must be recalled that rhythm is not a succession of jerks, but is basically a steady flow, a regular succession of similar impulses, the word rhythm itself coming from a Greek stem meaning "flow." Like all other good things, this theory of continuous movement may be carried to excess, and one occasionally sees conducting that has so much "back-stroke" that there is no definiteness of beat whatsoever; in other words there is no "bottom" to the beat, and consequently no precision in the conducting. But on the other hand, there is to be observed also a great deal of conducting in which the beats seem to be thought of as imaginary points, the conductor apparently feeling that it is his business to get from one to another of these points in as straight a line as possible, and with no relaxation of muscle whatever. Such conductors often imagine that they are being very definite and very precise indeed in their directing, and have sometimes been heard to remark that the singers or players whom they were leading seemed exceedingly stupid about following the beat, especially in the attacks. The real reason for sluggish rhythmic response and poor attacks is, however, more often to be laid at the door of a poorly executed beat by the conductor than to the stupidity of the chorus or orchestra.[7]
HOW TO SECURE A FIRM ATTACK
Coordinate with the discussion of continuous movement and back-stroke, the following principle should be noted: A preliminary movement sufficiently ample to be easily followed by the eye must be made before actually giving the beat upon which the singers or players are to begin the tone, if the attack is to be delivered with precision and confidence. Thus in the case of a composition beginning upon the first beat of a measure, the conductor holds the baton poised in full view of all performers, then, before actually bringing it down for the attack, he raises it slightly, this upward movement often corresponding to the back-stroke between an imaginary preceding beat and the actual beat with which the composition begins. When a composition begins upon the weak beat (e.g., the fourth beat of a four-pulse measure), the preceding strong beat itself, together with the back-stroke accompanying it, is often given as the preparation for the actual initial beat. In case this is done the conductor must guard against making this preliminary strong beat so prominent as to cause the performers to mistake it for the actual signal to begin. If the first phrase begins with an eighth-note (
), give a short beat for 4 and an extra up-beat for the first note of the phrase. If it begins with a sixteenth-note, do the same thing, but make the extra up-beat with which the first tone is to be coincident shorter and quicker. If a good attack cannot be secured in any other way, beat an entire preliminary measure until the attack goes well, then adopt some such plan as has just been suggested.
THE RELEASE
The preliminary up-beat which has just been discussed is equally valuable as a preparation for the "release" or "cut-off." The movement for the release is usually a down stroke to right or left, or even upward. It is customary not to beat out the final measure of a composition or a complete final section of a composition, but to bring the baton down a few inches for the first beat of the measure, and then to hold it poised in this position, either counting the beats mentally, or trusting to feeling to determine the time for stopping. A slight upward movement is then made just before the tone is to be released, and it is the warning conveyed by this preliminary movement that enables the performers to release the tone at the precise instant when the baton is brought down for the cut-off. It should be noted that the release must come at the end of the duration value of the final note. In 4-4 a final
