Note : This article
assumes some basic knowledge of theory; understanding of intervals and
basic construction of triads is recommended.
Let me start with some examples:
Play this simple progression: Am, Dm7/F(or simply a Dm/F), Am/E, E7, Am.
If you are like most guitar players, chances are you would probably play
something like:
Now compare how the above progression
sounds with this:

You probably noticed that the second
progression sounds very final (much more so than the first progression),
similar to something you would expect to hear at the very end of a piece.
What is the difference between the 2 progressions above? The chords are
exactly the same, so why does the second progression sound so much more
final and cohesive (and convincing)? The answer is in the way the chords
are voiced. In this article I would like to discuss some basic concepts
of voice leading and explain how understanding the principles will greatly
help you in your ability to write better chord progressions and songs.
When most guitarists begin to learn chords they learn “shapes” of chords
that become very familiar and recognizable over time. While this is a workable
approach in the beginning, it is bound to cause some problems in songwriting
eventually. The problem is that a lot of guitarists will tend to rely on
the familiar shapes they learned for chords but do not think very much
about the NOTES WITHIN THE CHORD. In other words, guitarists typically
only think about playing blocks of notes. This is easy to do on the guitar
because of the symmetrical nature of the instrument. As I said above this
is of course a workable approach and it has been used with great success
by many. However there is a lot of value to be discovered by thinking about
building chord progressions in a new way. Voice leading offers a new way
to think about structure in your chord progressions. Allow me to explain
what it is.
When I first began to study music theory with Tom
Hess and later, at Indiana University Jacob's
School of Music , I learned new ways of thinking about building progressions.
The “rules” (or rather accepted traditions) go back to old conventions
of classical composition when there were no “chords” to speak of and most
music was written for 4 voices (bass, tenor, alto and soprano). The music
was written for each part individually forming a melody. However because
of the way the parts intersected when they were written on the music staff,
they formed blocks that eventually came to be known as chords. This is
a very important concept. The notes of each of the 4 voices followed a
melodic pattern when looked at horizontally (on its own, the soprano line
was its own melody and the alto line was also its own melody, same as tenor
and bass). When they were written on the staff, the first note of the soprano
melody intersected with the first note of the alto melody and also intersected
with the first note of the tenor and bass melodies. When I say intersected
I mean that the first note of each of the parts was played or sung at the
same time the listener heard a single sonority (sound that was made up
by the intersection of the melodies). As the piece continued the melodies
continued to intersect and form chords that made up the piece.
So what does this mean for us as guitar players? It offers a NEW WAY OF
THINKING about writing chords. If you start treating your chord progressions
as multiple melodies (rather than random chunks of notes), you will immediately
add a new dimension to your music. Rather than thinking in blocks or shapes
as guitar players tend to do, you now have a new skill at your disposal.
The soprano melody (the highest sounding note of the chord) is especially
important to pay attention to because it is what the listener typically
hears most prominently. Along with soprano, the bass is the second most
important note so attention must be paid to treatment of the bass melody.
At the most basic level, the conventions of voice leading call for smooth
stepwise motion between the notes (voices). So if you follow this approach
when writing chord progressions for guitar you will notice that your progressions
will seem to flow much better and sound much better connected as well.
Try to think of the chord progression as having multiple melodic lines
within each chord.
To illustrate the point better, imagine that the A string (5 th string)
will be the bass part, the D string will be the tenor, the G string will
be alto and the B string will serve as the soprano. Try to keep the notes
for each part on its respective string. Now attempt to find as many ways
to play any of your favorite progressions sticking to the rules described
above (smooth melodic motion).
This means do not have wide leaps (intervallic jumps) in any of the parts.
This is particularly true of the tenor, alto and soprano melodies (your
D G and B strings). The bass is more free to make wide interval leaps.
Also if you can try to keep common notes the same. So lets say for example
that you are switching from B major/D# to E minor.

Notice that I kept the note in the alto (G string
4 th fret) the same when switching between the chords. (B is the root of
a B major chord and is the 5 th of the E minor chord).
Of course in order to be able to come up with progressions in the manner
described above would require you to have a good knowledge of the fretboard
because you will be forced to think of where the notes are that you need
to get in order to form each chord. So learning the fretboard better is
the added benefit of this exercise.
Earlier I mentioned that most guitarists rely on familiar shapes of chords
to write their songs. The reason why a lot of times the progressions don't
flow well together (or at least not as well as they could) is because the
intervals (distance) between the notes in the chords are spaced way too
far apart (as opposed to following a melodic step wise motion).
There is a lot more to the topic of voice leading and taking the time to
learn the skill will definitely pay off in giving you extra musical tools
you can use for music writing. I recommend studying with a great teacher
who can teach this subject well. Trying to learn music theory by yourself
can only lead to confusion and frustration.
In part 2 of this article I will discuss some more specific guidelines
that were usually followed in classical music.
