In the last lesson, WebRhythms covered meters in two-four, three-four, five-four, and seven-four. Each of those time signatures had the quarter note serving as the value of one count (remember that the upper number of the time signature signifies how many counts in a measure while the lower number indicates the note value of one count). In this lesson, we're going to take a look at some meters that use an eighth note for the value of a single count.
In a meter of six-four, each measure has the value of six quarter notes. In six-eight time, there are still six counts in the bar, but the eighth note (signified by the number eight), not the quarter, receives the value of one of those counts. This brings up an interesting question. If there are six counts in the measure, are there also six beats? The answer is sometimes yes and sometimes no.
In many meters, the terms of "beat" and "count" are interchangeable. In six-four time for example, there are six counts to the bar and also six beats - but in other meters, the number of counts and beats are not always the same. Let's take a look at the meter of six-eight. In these measures, there are six counts, but only two beats. How can this be? Meters are designated as either being "simple" or "compound".
I dislike terms as much as the next guy, but you've got to admit that knowing the proper musical terms makes communication easier. "The little black oval ball with the line sticking up from the side and the squiggly thing hanging down" is not as clear as saying "eighth note". The term simple meter can be defined as a meter that normally has beats divided into two even subdivisions. Compound meters have a basic pulse that is regularly divided into three parts.
In the first measure of the example above, the six eighth notes make up the six counts. To perform this measure, simply count the numbers from one to six and play a stroke on each number. But, as the tempo begins to get faster and faster, the six counts should be phrased as two big beats with three divisions each (ONE two three FOUR five six). This is what makes six-eight a compound meter--each of the two main beats has three subdivisions. If you're having trouble seeing how six counts can be placed into two beats, sing the children's song "Three Blind Mice" (quietly if there are friends around) and tap your foot with the main beats. Notice what happens when you get to: "CUT off their TAILS with a CARving KNIFE". In the space of two foot taps, count to six by putting count one on the first foot tap (cut) and count four on the second (tails). Now you should see how you can fit three counts into a single beat.
The second measure of the example above contains only two dotted quarter notes. You already know that a dotted quarter has the same value as three eighth notes, and because we're working in a compound meter, there are three eighths to each "beat". In other words, the eighth note receives the count, but the value of a dotted quarter note receives the beat. Each dotted quarter is subdivided into three eighths. In order to play this measure, place a stroke on counts one and four (you must still count the others).
The third measure is a little trickier than the previous two bars. In this measure, each beat consists of a quarter note and an eighth note. Each beat still contains the value of three eighths (or a dotted quarter note), but only the first and third counts of each beat are struck, because the quarter note has the value of two counts. When playing this measure, play strokes on counts one, three, four, and six. If this measure is repeated over and over, it will begin to sound like the ride cymbal pattern used in a standard shuffle beat.
The last bar in example one presents a new problem. What do you do with the sixteenth notes? I'll give you three hints. Remember that a sixteenth note divides an eighth note into two equal parts, the eighth note is getting the value of one count, and that the syllable "and" is used for the first subdivision of a count. The envelope please... Yes, the first beat in the fourth measure is counted as "one, two and, three and". Since the eighth note gets the count, and there are two sixteenths to each eighth, a single sixteenth has the value of one-half count. When you play this measure, be certain that the sixteenth notes are moving twice as fast as the eighth notes.
Most often, composers and copyists will do their best to beam notes together so that your eyes can take in three counts (one full beat) at a time, but it isn't always possible. Example 2 (in three-eight time) shows several figures that can't be beamed, either because they contain rests or a quarter note. While it is a little more difficult to quickly grasp that these figures have the value of a full beat, try to approach them as a single "word" instead of several different, independent symbols.
In the reading exercises in this WebRhythm lesson, there are meters of three-eight, four-eight, five-eight, six-eight, seven-eight, and nine-eight, each separated by the double barline. While some of these meters are compound (three, six, and nine), the four-eight meter is still a simple meter. In fact, a meter of four-eight is very similar to the meter of two-four. Each bar has the value of four eighths (or two quarters if you prefer).
The time signatures of five-eight and seven-eight aren't simple, but they're not compound either. These meters are typically called "complex" or "asymmetrical" (again, I think the name "complex" is a little negative), because the beat's subdivision values are not equal. The typical measure of seven-eight usually contains three beats (but always seven counts) which can be phrased as 2+2+3, 2+3+2, or 3+2+2. Because each beat can be subdivided into either two or three parts, the lengths of the various beats are not the same. In other words, a bar of seven-eight that is phrased as 3+2+2, has a longer first beat. In addition, the first beat is compound while the last two beats are simple. As you practice the exercise, notice that the phrasing of each measure is conveyed to you by the beams. If a group of three eighths are beamed together, then that is the compound beat in the bar.
I suggest that you begin practicing these
exercises slowly at first (gee, have you heard me say that before?),
bringing up the tempo only after you feel more secure. Also, in the
asymmetrical meters, try to get a feel for the basic pulse of the beats
by putting a small stress at the beginning of each beamed grouping (these
are the beats). As I said at the start of this lesson, odd meters are
only odd because they are less common. As you gain more experience in
reading them, they will become more "normal".
