Tuned Gongs

I haven’t updated the percussion section in quite a while.  Here’s a quick remedy.

Tuned Gongs.

First off, what is a gong?  By definition, a gong must have a definite pitch.  Therefore, the term “Tuned Gong” is redundant.  I use this term however because many times the term gong, especially in traditional orchestral scores, actually refers to a tam-tam.  Tam-tams will never have a definite pitch.  Tam-tams will have a flat surface, while often, gongs will have a raised center (called a nipple), though, this is by no means always the case.

Tuned Gongs will have a chime-like quality to their sound. They will  have the “splash” associated with a tam-tam at higher dynamics, but the pitch center will disappear.  Strict “in tuneness” is not a given with gongs as the act of sticking them will cause some pitch distortion, especially at higher dynamics.

Pitches available will vary widely.  Full chromatic sets are (or in some cases were) available from noted manufacturers.  A quick Google search shows that I can find pitches available from B-flat1 to C6 – just over four octaves.  (In case you’re curious, the total set is over $40,000.)  Individual gongs are usually purchased for the needs of a particular composition rather than full sets.  A complete set will be rare, but not impossible. http://www.steveweissmusic.com/product/tuned-thai-gongs/gongs

One major concern is space.  These instruments, when all put together will take up a large amount of real estate.  Performers will come up with all sorts of creative ways to arrange the instruments on stands, but with the lower pitched gongs, there will be large distances covered (sometimes feet or tens of feet).

One other concern is the length of each strike.  Left to their own device, a gong will resonate for a long time (though not usually as long as a Tam-Tam).  Specific durations will need to be dampened by the player’s free hand or by a second player.  Larger gongs have longer durations than so smaller gongs.

Vaughan William’s 8th Symphony.  This movement focuses on the tuned percussion and includes a major part for tuned gongs.  One of the great master’s overlooked works.

This video of Et exspecto… starts in the 5th Movement where there is a significant accompaniment from the gongs.  Note how the player has his gongs arranged.  Also note how, at 32:53 one of the gongs goes flying off the stand ne’er to be recovered.

Oh, the perils of percussion…


The Vibraphone is a curious instrument.  It is essentially a large metal Marimba.  The key difference between the Vibraphone and the Marimba are the rotating fans places in each of the Vibraphone’s resonators.  These fans, controlled by a variable speed motor, produce a vibrato effect not heard on any other percussion instrument.  This instrument was immediately popular in jazz.  In classical music, it had a cooler entry.

The Vibrato

The curious thing about the Vibraphone is that most times the characteristic vibrato is turned off in concert works.  In fact, many of the Vibraphones I’ve worked with before have had their motors disabled.  When writing for the Vibraphone, use of the motor must always be indicated.  As most Vibraphones will have a variable speed motor, it is also important to request the speed of the motor – slow, medium, fast.  I once wrote a piece where I indicated two separate Vibraphones.  One has the motor on the highest speed while the second had the motor turned down one notch from high.  This would produce a cross-vibrato effect where the instruments are slightly out of sync.  Another thing to think of here, Vibraphones from different manufacturers will have motors that rotate at different speeds.  The motor can be changed and turned on or off during a performance.  The best instruments will have a silent motor.

The Range

Traditionally, the range of the Vibraphone has only been 3 octaves from F3 to F6, but increasingly, makers are now making instruments with a four octave range from C3 to C7.  I find it odd that it took so long for the Vibraphone to have its range extended when the Marimba constantly undergoes range extensions.  I prefer the 4 octave instrument.  The extra bass notes really add a new sound to the instrument.

The Bow

An interesting effect is to take a cello or bass bow and actually bow the edge of the bar instead of striking it with a mallet.  This is a very slow technique.  Changing from the top row to the bottom row (black keys to white keys) take a considerable amount of movement.  In the piece I mentioned above, I had one of the Vibraphone players play only the top row while the other only played the bottom row to lessen the movement of the players.

The Ring and the Pedal

Because the instrument’s bars are metal, they will have a very long ring after they are sounded.  The larger bars will ring longer than the smaller ones.  Because of this, the Vibraphone is equipped with a pedal exactly like the sustain pedal on a Piano.  Pedal markings should be included in parts for exact clarity.  Otherwise, the performer will pedal the part at their discretion.  If the pedal is not depressed, the Vibraphone will have a dry staccato sound.

Mallet technique

Vibraphones will use either two or four mallets.  Two-mallet passages will generally be single lines while four-mallet passages will contain chords.  In chords it is best to keep notes spacing to about an octave between mallets held in one hand.  Check with a competent player for limitations of four-mallet technique.  Six-mallet technique is known, but extremely rare.

Pitch bending

A rarely used technique involves bending the pitch.  This is done by sticking the bar with one mallet and then dragging a second mallet across the bar.  See video below for how technique is done.

Staff Bells

Staff Bells are one of the most underutilized percussion instruments in existence.  They are essentially suspended handbells stuck with mallets.  Staff Bells were originally used in the early 1900s as a novelty act in vaudville shows.  The Deagan Company (who worked to develop the Marimba, Vibraphone, and the unsuccessful Nabimba) marketed these for several years.  The only composer who seemed to latch onto them was Percy Grainger.  Grainger used them extensively in The Warriors, In a Nutshell Suite, and in the finale of Lincolnshire Posy.

If a suitable rack can be built, any set of handbells can be turned into Staff Bells easily.  Usually the clappers are removed from Staff Bells.  Depending on the size of the bell, the mallet can be hard rubber, plastic, or yarn/cord.  Hard mallets can damage the larger bells.  Soft mallets will not produce an audible sound on the small bells.  If a large range is expected, it is best to split the Staff Bells up among 2-3 players.  Grainger almost always uses 3.

Range is conceivably 7 octaves depending on the maker of handbells.  Schulmerich makes a range from C2 to C( (sounding an octave higher).  The C9 (really C10) is one of the highest musical instruments in existence an octave higher than the Piano’s highest note. Four to five octaves is the standard (C3-C7).

Bell Plates

Bell Plates are one of the many attempts to recreate the sound of massive, deep church bells.  The result isn’t a perfect simulacrum, but they are an interesting and useful sound in and of themselves.

Depending on the maker, Bell Plates will come in many different sizes.  Chromatic sets are preferred.  I have seen them advertised in up to four-octave sets going down to C2 (the C below the bass clef).

The sound of Bell Plates will last a long time after they are struck (up to a minute or more).  Care should be taken to notate the exact duration of the ring.

Different mallets can be used from a rawhide Chimes beater, to a timpani stick, to a bass drum/gong beater, to yarn mallets.  Each will produce a strikingly different result.

Crotales and Antique Cymbals

One of my favorite percussion instruments are the Crotales.  Crotales are tuned metal disks usually stuck with hard mallets (plastic or metal) that sound similar to a Glockenspiel.  Crotales will only ever have a 2-octave range (top two octaves of the piano).  Only rare experiments have extended the range beyond this.

In terms of sound, I tend to think of Crotales as having a more oboe-like sound while the Glockenspiel will have a more clarinet-like sound.  This has to do with the complex series of overtones produced on the Crotales.  Think of them as twinkling lights in the night sky.

Technique on the Crotales will be the slowest of all the mallet percussion instruments due to the shape of the discs.  Bowing the discs will give a pure, if not eerie sound that is highly effective.  Bowing technique is only for extremely slow passages (half and whole notes at most).  The ring time is the longest of any of the traditional mallet percussion instruments.

Antique Cymbals

Antique Cymbals are the exact same instrument as Crotales only played in a completely different manner.  Like their name implies, pairs of them are struck together like cymbals.  These are some of the oldest pitched percussion instrument that we know of.  Berlioz remarks that several were found in Roman ruins (hence the name “antique”).  Famous examples of Antique Cymbals are found in “The Queen Mab Scherzo” from Berlioz’s Romeo and Juliet, Prelude to the Afternoon of a Faun, and The Rite of Spring.

Another rarely used tuned percussion instrument are the Almglocken.  Almglocken are tuned Swiss cowbells.  They usually come in sets ranging from 2 to 4 octaves.  Almglocken have had their clappers removed, so to sound them they are stuck with mallets (yarn or rubber) like most other tuned percussion instruments.  There are three ways Almglocken can be mounted.

1. Fixed on a rack, unmoveable, most common

2. Lying flat on a table, produces a dampening effect

3. suspended from a rack, free swinging, can produce a “vibrato” effect

If not specified, the first option is the most common.

The dull plunk has little sustain, and the intonation is not 100% accurate.  I find it best to use Almglocken by themselves and not part of a larger percussion ensemble.  I’ve written for the instrument once as an accompaniment line in a quiet section of my Bassoon Concerto.

Introduction to Almglocken

Suspended Almglocken

The most well-known work that scores for Almglocken is Messiaen’s Et Exspecto Resurrectionem Mortuorum.  This work uses 4 octaves of Almglocken divided among three players.

The Chiapas Marimba and the Nabimba

The modern Marimba is a long way from its ancestor.  The original Marimba still exists, but is almost unheard of in concert music.  I’m referring to the Chiapas Marimba, an ethnic instrument from the state of Chiapas in Mexico.  (Yes, I’m aware that the Marimba has earlier origins in Africa, but that will delve too deep into ethnomusicology for the purposes of orchestration).

The Chiapas Marimba differs from the concert Marimba in that the resonators (almost always made of dried gourds) are equipped with buzzing membranes that give the instrument a reedy, almost saxophone-like sound.  The range is often times must larger as well.  A few years ago, 5-octave Marimbas were rarities (though this has now changed), but Chiapas Marimbas have always had 5-6 octaves.  The 6 octave instruments are larger than any current Marimba in production.  These instruments will usually have a half-octave added on to the normal 5-octave range (F1 – F7).

The sound can be used in completely different ways than the normal Marimba, especially in the lower register.  A roll on the low notes will become almost seamless and will add to an overall bass.  Arpeggios will have a richer quality to them without the harsh attack of the Marimba.

Note: nearly all the time, the Chiapas Marimba is played by multiple people (2-3).  These instruments are so large (up to 10.5 feet in length) that accommodating more than one person is easy.

Surprisingly, the first American-made Marimbas made were much closer to the design of these Chiapas instruments.  The Deagan company basically invented the modern Marimba.  Their first instruments were called “Nabimbas.” Only a handful of these instruments were made.  Outwardly, they look like a modern Marimba, but the buzzing resonators give a sound almost identical to the Chiapas instruments.  Only a single work in the literature calls for a Nabimba, Percy Grainger’s In a Nutshell Suite from 1912, which incidentally is also the very first composition to ever score for a Marimba as well.  Deagan offered these instruments up to a 5-octave range.

These two instruments, while outwardly different, are virtually the same.  It can add a completely new color to the percussion section, and can easily blend with the reed instruments.
