Warmup and Intonation
Thomas A. Labadorf
A warmup routine has long been professed as the most important part of a daily practice because it prepares our muscle groups for the challenges we encounter during performance. But besides being prepared for the physical demands of clarinet performance, it is also important to ready our minds so we can control these muscle groups to produce a fine musical performance. My own warmup routine, which combines aspects of both of these areas, is drawn from various sources and experiences to form a single and efficient warmup procedure.
These exercises can be easily included as a starting point to any warmup routine. (Spring, 1995) The printed exercise contains three parts. The first takes advantage of long tones arranged in open fifths, fourths and octaves; the second adds the second and third in a higher octave to fill out the first part of a major scale; and the third continues into a higher range including the remaining scale tones of the sixth and seventh. When practiced carefully, this preliminary warmup procedure will ready your performance in areas that include a number of different technical and musical areas - namely, tone and embouchure development, breath control, legato fingering, phrasing, and tempo and pitch awareness. This first warmup step should precede exercises that concentrate on digital dexterity and articulation.
The most unique part of this warmup is its concentration on intonation. For this, you will need a tuner that can generate a steady, reliable pitch to tune against. Another important feature of a tuner is calibration. For proper warmup and tone production, it is important not to stress the embouchure beyond what is reasonable in order to play in tune. A cold instrument will play flat, and so the tuner must be calibrated to tune to the instrument. As the instrument warms, its pitch will rise gradually, and thus the calibration of the tuner must be raised until it reaches A-440. After this point, adjustments need to be made to the clarinet to match the A-440 standard sounding from the tuner.
Before attempting this exercise as an intonation study, it is important to understand why we use equal temperament as a tuning standard. Tempered tuning became an issue when the organ was becoming an important musical instrument in the late 1400s. (Randel 1986, p. 837) Up to this time, there was no need for a tempered scale since the major instruments of the time (mainly the voice) were able to tune each note to perfect intervals prescribed by Pythagoras centuries earlier. This is something a keyboard instrument was not able to accomplish since its pitches were not immediately serviceable. As keyboard instruments became more popular, and music more complex, the intonation of these instruments had to be tempered to make them acceptable for performance in different keys. Many versions of tempered scales were created along with considerable debates over which were best. Eventually, the tuning standard settled on equal temperament to which all western instruments are tuned today. The important thing to remember is that temperament was developed to make the tuning of keyboard instruments acceptable for the performance of music in all keys. Studies have shown that musicians who play instruments with serviceable pitches (e.g., unfretted strings, woodwinds, etc.) tend to play in just and Pythagorean intervals rather than equal temperament even though their instruments are tuned to equal temperament. (Backus 1969, p. 130)
Exclusive use of the tuner's visual meter as a tuning aid will do little good unless we intend to perform exclusively with pianos. Tuning one note against another involves reacting to beats and difference tones that are acoustically generated when two pitches are sounded simultaneously. Some pitches may require considerable adjustment in order to sound in tune. For example, a D5 played as a fifth of G4 will be treated differently than as a third of B-flat4. (The octave notation used in this article is U.S.A. Standard transposed to B-flat unless otherwise noted) Our ears are the best judge of this pitch placement, since the meter on a tuner will show your pitch deviation against a standard matching its internal equal temperament.
The Exercise

For a printable version of the exercise, go to My Website.
The exercise is in three parts. The first contains three bar units with
intervals of fourths, fifths and octaves. There are eleven of these units
each starting a half step higher than the last. The last unit of this part
starts on an E-flat4. The tuner emits a tone matching the first note of
each unit. The goal in this section is to eliminate any beats created
between these perfect intervals.

The second part starts on an E3, and adds the sixth and
seventh degrees of the scale in the clarinet register. This unit is repeated,
each time transposed one half step higher, the last unit starting on B–flat3.
The tuner sounds an E4 as it continues to rise chromatically out of the
first part. Set the tuner to E3 (see bracketed note above) if the intervals
are difficult to hear. By listening carefully, you should hear the tones
created as a result of the difference in frequency between your pitch and
the pitch emitted from the tuner (see notes in parenthesis above). The
clarity of these different tones may depend on your proximity to the tuner.
If you can't hear them plainly, try moving around the tuner. Make adjustments
to your pitch to precisely tune these notes. If you have a free hand (or
a friend who is willing to help), switch the tuner to visual meter to
see how your acoustically tuned pitch compares to the tuner's equal
temperament. Depending on the interval, you may notice a discrepancy
between what you tune acoustically and what the meter reads. Trust your ears!

The third part is an extension of the second adding the second and third scale steps in the clarinet register. As in Parts 1 and 2, each unit is repeated transposed one half step higher than the last. The last unit can be as high as you feel comfortable. Again, pitches in parenthesis illustrate the difference tones created as a result of the difference in frequency between your pitch and the tuner's. Because this part includes the second and third degrees of the major scale, treatment of these notes will be different than any other yet played. Arrows above the notes show which direction you need to play your pitches in order to tune the difference tones. Numbers above the arrows illustrate approximate deviation in cents from the tuner's equal temperament.
