Several years ago, I attended a conducting clinic where a major controversy arose which I didn't fully understand or appreciate at the time. The clinician made a number of veiled references to an entire “school" of band conductors who did not believe in actually conducting during rehearsals but instead used an amplified metronome to keep time.  Some of the clinician’s comments were clearly political and directed against this particular methodology.  Since then I have learned that a rather large number of high school band directors in Texas rehearse almost exclusively using an amplified metronome. Apparently, this is a highly emotional issue in Texas with directors split into camps for and against.
 
I have recently seen increased use of metronomes in ensemble rehearsals in New Jersey. While the emotional biases have not risen to the fever pitch apparently found in Texas, the trend does beg further thought. When thinking about this issue, two questions arise immediately.
  1. What is the benefit of using a metronome?
  2. Should band conductors use an amplified metronome during full band rehearsals? If so, how should it be used?
Virtually all musicians recognize the value of using a metronome when practicing to help stabilize pulse and to work to refine technique. Most serious instrumentalists regularly use one when practicing. However, individual practice is very different from ensemble rehearsal.

Using a metronome in rehearsal might be valuable for the same reasons as in individual practice. The first and most obvious goal would be to stabilize tempo. Probably for both psychological and practical reasons, students respond to the sound of the metronome more naturally than watching the conductor in terms of keeping the pulse absolutely steady. The metronome does not lie, and even the best conductor will follow the group to some degree.
 
Certainly keeping a steady pulse is a positive step in helping to develop students’ rhythmic maturity. There are numerous and legendary stories about the great band conductors of the past, notably William Revelli, spending countless rehearsal hours practicing marches at slow tempi with only the tubas, horns, and percussion playing so that the pulse would be absolutely steady and precise. Using a metronome would not seem much different.

Just as in individual practice, a metronome would be best used when the music has an unchanging tempo and the goal is largely technical mastery. The pulse can be gradually increased for passages that are technically difficult. The ensemble is essentially engaged in group practice in these kinds of rehearsals.

Using a metronome changes the players’ psychological focus. The clicking automatically implies a technical orientation implicit in practice. Conductors might choose to use it when the goal is pure technique. Musical expression might want to be divorced from technical mastery.
 
However, there are some possible major negatives to balance the above positives. Students may not develop their own internal sense of pulse if too much reliance is placed on the use of the metronome. Even after the metronome is turned off, students may already have established the pulse through something resembling muscle memory. Second, the tempo, and therefore interpretation, of the music may become very wooden and rigid. Also with overuse, students may just not be able to follow the conductor. They may get so used to reacting to sound, that they might not follow visual signals very well. The conductor himself or herself may become something of an automaton not really able to lead the ensemble.
 
Students must develop their own sense of pulse. They must be able to internalize the beat and its subdivision. It is this goal that is probably at the center of the controversy over using a metronome in rehearsal maybe even more so than the problems with rigid interpretation. If the metronome is constantly used, will students internalize the pulse on their own? This is a very difficult, if not impossible, question to answer.

Tuning Machines

Although a different issue, the use of tuners is somewhat related. What metronomes are to rhythm, tuners are to intonation.

Many band and orchestra teachers make extensive use of tuning machines. In a number of band rooms, each student has a tuner on his/her music stand. A student can watch the readout and adjust her/his intonation accordingly.

Tuners are very valuable tools in providing instant feedback about tuning. This kind of ear training is very difficult for students to learn and giving them instantaneous, visual feedback is of tremendous educational benefit. The time devoted to full ensemble tuning can be greatly reduced when using multiple machines. Students can check themselves very quickly, even before the actual rehearsal begins.
 
Intonation problems arise often during the course of a rehearsal. One reason is because of the scale of all wind instruments is so tremendously uneven. Certain notes are very out-of-tune, even when the instrument seems to be in perfect adjustment. There are countless examples of real problem areas (i.e., clarinet throat tones, flute C, C#, trumpet concert C, to name just a few). Tuning changes with different dynamics. Using a tuner can help students to get a grasp on intonation tendencies.

However, students can become totally dependent on tuners and fail to critically listen. And unlike rhythm, intonation is rather subjective in the real world because of the constantly shifting nature of pitch. There are so many different variables when it comes to intonation. If students cannot hear, they will always be limited.

To use them or not?

So what is the answer to the question?  Should conductors make use of these machines or not?

Obviously, students and teachers in their daily musical work, for practice and study should use metronomes and tuners. The real question then is if they should be used in full rehearsal or not. Many conductors believe that they should not be used in this way. Others, notably the aforementioned conductors in Texas, hold that there is no better way to build technical mastery.

It is my opinion that the balance lies somewhere in the middle. Metronomes and tuners can be valuable tools — machines to assist learning. However, when overused, they can become crutches where students cannot function without them.  As long as these devices further student learning, then their use should be encouraged — but only in moderation. My guess is that it would be very easy to use them too much and too often.

As in so many facets of education, success in the classroom falls on the shoulders of the teacher. In the hands of a wonderful conductor/teacher, these machines can be extremely effective. When less inspired teachers expect them to automatically build a keen sense of pitch and rhythm in their students, the result will probably be less than successful. The machine does not teach.
 
So my recommendation is: use them but use them with great restraint and with a clear sense of educational purpose.
