Eight Days A Week

It was recently brought to my attention that I haven't been
upholding my end of this blogging arrangement, ie. - I was a
couple months behind again!

The problem is that I haven’t had time! Who has the time for
anything these days, with the pipe band season picking up, the
kids in soccer and baseball, teaching everyday...
With each week getting busier and busier and the hours, days,
weeks and months flying by, I find myself wishing I could slow
down time. Hmm, perhaps that’s possible. The problem, really,
is that I need to add time, and that's not possible!

What the heck is “time” anyway?

A quick dictionary search will bring up about a hundred
definitions for time, but, how’s this one: “a system of
measuring duration”? I like this, because we can relate this
concept to music!

Music only exists in relation to time.

Every piece of music is played in relation to time, dependent on
the time signature and tempo. If we play 30 measures of music
in 4/4 time at 120 beats per minute, we create 1 minute of music
which exists as a physical entity for those 60 seconds only. It
does not exist before or after. (Sometimes this is a good thing!)
Music is created by combinations of sound and silence, and
organized by time (meter and tempo).

Music, like time, can be explained mathematically.

Einstein proved that perceptions of time are relative, and not
absolute. That’s fine for Einstein but, for musicians, we need
absolutes. We, as musicians playing together and playing
“in time”, need an absolute starting point, an absolute ending
point, and absolute landmarks along the way, in order to play
in proper unison.
These absolutes are important to the listener as well, because
the brain requires order to process information. Music without
an absolute start and end point and without the proper mechanics
(rhythmic pulsing, cadence, tension, resolution, etc) could not
be preceived as music by the listener.

In music, we use a metronome to measure time.

Thinking of our earlier example, if we play 30 measures of
music in 4/4 time at 120 bpm, we’re playing a given amount of
time as determined by the metronome.

We have our absolute staring point
(A) = beat #1 of measure 1 at time :00 -
and our absolute end point
(B) = beat #1 of the silent measure 31 at time :60.
But what happens along the way from A to B?
The metronome will click out every beat in each measure along
the way, from A to B, in equally spaced intervals. In this example,
the metronome will click one beat every half second, or two beats
every second for one minute.
Although the metronome will never waiver in it’s spacing
between clicks, sometimes the musician will choose to play “off
the click” for musical effect.

Think of every beat as having 3 possible attack points: dead
centre (we call this the “pocket”), slightly in front of centre, or
slightly back of centre. Playing ahead, behind or in the pocket
will greatly change the overall feel of the music for the listener.
But, what if this slight shifting of beat placement isn’t enough to
achieve what the musician is trying to express? Answer:
We play “off the click”.

This is an important technique in bagpipe music because the
instrument itself has some significant limitations in the sound
it’s able to produce. The bagpipe is limited in its range, unable
to vary its volume, produces only legato notes, is unable to play
rests, and no one knows how to tune the things.
Subtle variations in articulation become extremely important
in giving traditional bagpipe music shape.

Pipers compensate and add expression to their music by
varying the length of the beats within a measure or phrase. We
refer to this as long and short note articulation, and it's a
form of rhythmic dynamics.

The important thing to remember is that, with the start and end
points (the time, in other words) predetermined, we need to be
careful that all our long and short beats add up mathematicaly
correct in the end, (so that A eventually lands cleanly on B). This
is where our landmarks come into play. Landmarks should fall
precisely in the pocket (the more precisely they land, the "deeper
the pocket") and, the more landmarks we have along the way, the
more solid our time will be.
The best and most effective (and most musical) way to do this
is to start every bar of triple or quadruple time (3/4, 9/8, 4/4 or
12/8) in the pocket, and every two measures of duple time (2/4 or
6/8) in the pocket, as a general rule.
Using 4/4 (standard) time as an example again... beat one of
each measure should land deep in the pocket, and the remaining
beats have room to move on or off the click at the musician’s
discretion (provided that the next beat 1 lands in the pocket again).

So, here’s the deal:
If, in 4/4 time, every beat 1 landmark falls precisely in the
pocket with consistency, we can give each measure a relative
value of 100%. Hence, 100 is the sum of our 4 beats in every
measure.
The metronome, with its equally spaced intervals will, therefore,
assign a value of 25% to each beat in each measure:










The musician, however, may assign different values to each beat
note to change the rhythmic feel of the piece. Such as, the
following for a strathspey:










Notice that the measure still adds up to 100%. The attack point of
every beat 1 will land in the pocket producing landmarks for the
musician and points of reference for the listener.
The key to remember is that you can not add time! I hear the
following time and time again, and, I'd say this is the biggest cause
of ensemble phrasing problems in band playing:









Remember... music, and time, are products of the universe and
follow all the same rules. Every action must have an equal or
opposite reaction. If you add time somewhere, you must subtract
time somewhere else.

Music is mathematics, music is time, music is life.

And... we're out of time... (for now)

Cheers!
