Ontogeny Recapitulates Phylogeny, or: the
Overtone Series as a Basis for Warm-Ups and Essential
Technique
By Jeffrey Agrell
Ontogeny Recapitulates Phylogeny: the theory in biology
that development of the embryo retraces the evolutionary
development of the entire species. Although this theory has
proved not to be true, I nevertheless fastened on the idea
that it might have something to offer us when translated to
horn playing. Let’s take a quick scan over horn history how
we might apply the theory and use the significant events of
horn history to inform how a horn player might structure
his/her practice today.
Brass playing may have had its earliest roots in an
accident many thousands of years ago when someone happened
to stumble over the horn of an ancient oryx, kudu, or
eland, and, in trying to blow the dust out through the
broken tip, had his lips set in vibration – imagine his
surprise at the mighty blast! This short horn was capable
of only one or two notes, but for many centuries, that was
sufficient for the purposes of signaling for the soldier or
the hunter. Brass playing as we know it began to take shape
in about the fifteenth century, and in the sixteenth
century the horn (now made of brass tubing) started to grow
in length and be coiled. This longer instrument was capable
of producing more (playable) overtones of the Overtone (or
Harmonic) Series, which can be numbered from the
fundamental:
Players learned to use the air and embouchure to pick out
selected overtones and thus play melodies. Different keys
were achieved by adding different lengths of tubing, called
crooks. By 1750 the system of producing all notes of the
chromatic scale through the technique of hand stopping had
been codified and widely taught. Valves were invented in
1815, although at first they were seen simply as a way to
change crooks quickly since the main technique was still
hand horn. Although the French were notable holdouts, as
the nineteenth century went on, players began using the
valves as we do today to move quickly from note to note.
The F/Bb double horn was invented by Kruspe in 1897. In the
twentieth century, knowledge of the horn’s historical
valveless technique gradually slipped away as players spent
almost all their time thinking of fingering (valve
technique) and less in terms of different horn keys and
overtone series.
Let’s take each element of history (~phylogeny) and
experiment how we might use it to structure a player’s
practice (~ontogeny).
Playing begins with a first tone. Our version is going to
be much more refined than that Ur-oryx blast. Our
first tone may be a buzz on the mouthpiece, something
controlled and comfortable, like a waver-free long tone in
the middle register. The mouthpiece is the producer of
sound (the horn is really just an amplifier) and is
merciless in what it reveals (the horn is much more
forgiving – believe it or not). We can also try short
scales, intervals, and glissandos on the mouthpiece as we
warm up and recalibrate the process of brass playing.
Early players produced all tones without valves, acquiring
great skill in the control of air and embouchure to get
around the overtone series. Much more of horn history was
valveless than valved. Applying our theory, it is clear
that it would behoove us to spend a significant amount of
time playing “natural” horn only, i.e. playing only on the
overtone series before we add valve technique. Let us do as
the early players did, enjoying the added advantage of
being able to play successively on the overtone series of
many horns.
What we call the double horn is actually fourteen horns of
different lengths (i.e. one for each unique fingering).
Each length has the same overtone series [OTS] as above,
just beginning on a different pitch and thus playing in a
different key. For warm-ups and the development of
technique it is very useful to repeat overtone series
exercises on each “horn.” It is also useful to think in
terms of playing in each different key of horn rather than
just the fingering for each.
Below are listed all of these different horns with the
fingering (i.e. length of tubing) required to produce each
key (omitting the two overlapping keys). In brackets is the
equivalent note on the F horn.
F side (descending)
F horn = 0 [middle C]
E horn = 2 [B]
Eb horn = 1 [Bb]
D horn = 12 [A]
Db horn = 23 [Ab]
C horn = 13 [G]
B horn = 123 (F#]
Bb side (ascending)
Gb horn = T23 [Db, a half step above F horn = 0]
G horn = T12 [D]
Ab alto horn = T1 [Eb]
A alto horn = T2 [E]
Bb alto horn = T0 [F]
To apply our theory, we need to invent exercises to
aid in mastering movement around the overtone series. There
are nearly limitless variations possible, but knowing some
basic principles can help us quickly set up some practical
exercises for daily warm-ups and technique training. There
are three basic kinds of OTS exercises: adjacent note
(where you move from one note on the overtone series to the
next one), nonadjacent or “leap” exercises (where you jump
over one or more OTS note), and mixed exercises with both
adjacent and nonadjacent movement.
Many method books feature OTS exercises, but most of them
follow one rule that follows mistaken logic: they use
arpeggios that fit music theory rather than the
way the instrument works. That is, they avoid the
“out-of-tune’ harmonics 7 and 11 in order to produce ‘pure’
major arpeggios. It makes more ‘horn sense’ to spend time
first mastering adjacent note movement – including OTS 7
& 11 - before adding the more treacherous leaps. To
refer to our analogy, an embryo’s development is
continuous, moving seamlessly from one stage of development
to the next in very small steps – no skipping ahead!
Many of these OTS major scale arpeggios in existing method
books also immediately span the entire range of the horn.
For the purpose of warming up and recalibrating it makes
more sense to begin with narrower arpeggios in the middle
range and then gradually extend the range in both
directions. How quickly a wide range is achieved depends on
the player’s skill, experience, and perhaps the condition
of the chops today, right now. Whatever our level, we can
“recapitulate” the development of range and technical skill
each day at our own rate. Slur all exercises at first;
later use a variety of articulations. Begin comfortably,
slowly and accurately; increase speed gradually as
proficiency develops. Spending one-half to three-fourths of
your first session on OTS exercises pays big dividends. NB:
don’t write out the exercises any more than necessary –
learn the principles and then create exercises from them on
the spot each day. You’ll save paper and the exercises will
‘”fit” you much better. Creating the exercises this way
also has the advantage of variety – you can make them a bit
different every time while getting the same musical and
technical “vitamins” and not become bored and inattentive
playing the same exercises every day, day after
day.
One more thing: the OTS exercises of many method
books use only the F side of the horn. There is no reason
not to do them all on the Bb side as well, since that is
where we spend the lion’s share of our playing time. Thus:
all exercises should be done in all keys on both side
of the horn.
Adjacent
OTS note exercises
The journey of a
thousand miles begins with a single step. It makes sense to
begin with something that we can play easily, accurately,
and without tension. It is very important to be concerned
with the process of proper playing and not force the
product (e.g. using left hand pressure to force high
notes). Begin where everything is easy, then maintain that
feeling as you gradually expand the challenges (range,
dynamics, tempo, articulation, etc.). An appropriate place
to start might be two notes in the middle range.
1. Two notes. Start by simply going back
and forth between two adjacent overtones as smoothly and
efficiently as possible. Close your eyes; be aware of the
sensation. Speed should be slower to start; then gradually
increase tempo as proficiency develops - to the point of
trilling or tremolo. Example: OTS steps 5 to 6 (shown
below), 6 to 7, 4 to 5. Note that this “shape” becomes what
we will later practice as a lip trill when we move it to
OTS steps 8-9. Take this exercise through all “horns”
available, i.e. horns in C, Db, D, Eb, E, F, Gb, G, Ab, A,
Bb alto.
2. Three notes. After a two note warm-up
and recalibration, we begin to add notes. Start with an
up-and-back triplet shape on the lower two followed by the
same on the upper two. Then play up-and-back on all three.
Over time, experiment with moving this 'frame' of three up
and down the OTS. The higher the OTS numbers, the smaller
the intervals between the notes. Once again, take the shape
through all horns (keys).
A comfortable place to begin is OTS notes 4 5 6. Two
variations are shown here: OTS 4545 6565 and 3454. There
are more possibilities: discover them!
3. More than three
notes. Extend the above examples over wider ranges
and create new combinations. Examples: OTS notes 4-5-6-7-8;
5-6-7-8-9-10; 8-9-10-11-12 – this group (written C5-G5) is
especially rich with possibilities, since it is part of a
major scale (well, almost –the 11, usually written as F#,
sounds halfway between F and F#). Octaves also make
excellent practice ranges (e.g. 4 to 8, 5 to 10, 6 to 12, 8
to 16).
Sample exercises using OTS notes 8 through 12 on the C horn
[F: 13]:
As with all of these exercises, take this one through all
horns on both sides of the double, from C basso (shown; F:
13) to Bb alto (Bb: 0), which has a top note of high C (C6
[c’’’]). And, as with all exercises, don’t force it. Play
up through as many “horns” as is easy and comfortable using
air and embouchure without help from the left arm, and stop
there – don’t force the upper register. Keep at it, keep
coming back, keep observing the process and it will come.
4. Glissandos. Speed up octave exercises
to make OTS octave glissandos in all ‘horns,’ in all
registers. Start with one octave (e.g. C4-C5 = OTS notes 4
to 8, F: 0) and go up (and/or down) by half steps. Later
make it an octave and a half, then two, and finally three
octaves. Eventually you will find yourself able to do
octave glissandos that end considerably above high C, but
it should always come easily. At no time should you force
the top notes. Development and progress take time, and
everyone progresses at their own rate. When the top notes
don’t happen, stop, rest, and try again later.
Nonadjacent
OTS exercises (leaps)
When moving from
overtone to overtone starts feeling fluent, controlled, and
easy, start adding leaps to your program. Leaps are simply
very fast glissandos where you elide quickly and cleanly
over the middle note(s). Practice slurred leaps both
ascending and descending.
1. Start with basic, short (two-note), midrange leaps.
Examples: OTS #s 4-6, 6-8, 6-8, 6-9, 8-10. For yourself
make a chart of all possible two note OTS leaps. Select one
or more each day, beginning with narrower leaps and
gradually progressing to wider and wider intervals.
2. Combine several of these to
make longer exercises. Examples: OTS #s: 3-5-4-6 (also
practice it inverted: 6-4-5-3), 8-10-9-7.
3. Add leaps of several OTS notes. Combine freely with
two-note leaps, which will often make it easier to play
normal triads. Examples: 4-6-5-8, 5-10-8-12.
Mixed
Adjacent and Nonadjacent OTS exercises
This means playing arpeggios
using a mix of adjacent and nonadjacent notes (OTS number
leaps). As the notes grow progressively closer together in
the upper register, one or more OTS notes will have to be
skipped to maintain a regular arpeggio. Practice both
stepwise motion (scalar) and leaps (e.g. major triad) in
OTS notes 8 and above, especially #s 8-12. Increase speed
as facility develops.
Additional
Study
•Practice diatonic sequence
patterns (“shapes”) on the OTS, especially from OTS #8 on
up. Example: Down One and Back: an ascending sequence for
the OTS 4 to 8 octave (C4-C5) would be (in OTS numbers): 4
3 4 5 4 5 6 5 6 7 6 7 8. Descend using the inverted shape:
8 9 8 7 8 7 6 7 6 5 6 5 4 5 4. Move this shape up and down
in octaves for practice in all registers. Discover more
such patterns and put them to use.
•Play simple diatonic folk tunes that can be played using
only the OTS.
•Review OTS exercises in books by Wendell Rider, Frøydis
Ree Wekre, Fred Teuber, Douglas Hill, Philip Farkas, Louis
Dufresne, Sam Pilafian, and others. as well as books for
the other brasses to build a vocabulary of possibilities.
Be inspired and invent your own exercises and combinations.
With some imagination your OTS workout can be fresh and new
every day.
Valve
technique?
Our analogy must stop for
reasons of space with an overview of the development of
technique using the overtone series. Another analogy from
another science might say that the overtone series is the
operating system and the valves are the user interface.
After a thorough grounding in the ways and wonders of the
negotiation of the OTS, valve technique will come a lot
quicker, since technical problems are often due to an
underlying deficiency of skill getting around the OTS and
not with valve technique. Thus, the sooner the player
acquires fluency and consistent accuracy in moving around
the OTS, the quicker advances in valve technique will
come.
