Whole-Tube and Half-Tube Instruments and the Pedal Range

In his classic text, Orchestration, Cecil Forsyth talked about brass instruments being classified into two categories – whole-tube instruments and half-tube instruments.

Whole-Tube Instrument – a brass instrument capable of playing its fundamental pitch (the so-called pedal tone).

Half-Tube Instrument – a brass instrument that cannot play its fundamental pitch.

Forsyth was never clear as to which instruments fell exactly into what category.  In general, he stated that tubas were most definitely whole-tube instruments while trumpets and cornets cannot.  He neglects to mention trombones in either category, but includes passages that show pedal tones.

Trumpet vs. Cornet vs. Flugelhorn

While all played by the same performer, the Trumpet, Cornet, and Flugelhorn are all in different families of brass instruments and all have different sound qualities.  Knowing the differences between the three instruments is essential for good band and orchestral writing.

The B-flat Trumpet, B-flat Cornet, and B-flat Flugelhorn all have the same range, but it’s a combination of bore structure and mouthpiece design that give these three instruments wholly different characters.

B-flat Baritone Horn

Baritone Horn

This is the lowest member of the cornet family.  It looks like a skinny Euphonium, but is not.  For decades, the terms “Baritone” and Euphonium were interchangeable.  However today, most composers, players, and band directors are savvy enough to know the difference.  The British brass bands have always known the difference between the two and provided two parts for each the Baritone Horn and the Euphonium in their ensembles.

E-flat Alto Horn (Tenor Horn)

Alto Horn

This instrument is a taxonomic conundrum.  It is shaped like the tubas, and has some of the characteristics of that family, but due to its narrower bore structure, I place it here with the cornets.  If we look at the British brass bands, we will see that this is how they are grouped (as the middle voices in a cornet choir).  Early in the history of American bands, the Alto Horn, then known as the E-flat Horn, was seen in nearly all groups as a substitute for the Horn.  However, the Alto Horn is not a substitute for the noble Horn at all, and should never be treated as such.  Continue reading “E-flat Alto Horn (Tenor Horn)”

B-flat Cornet

B-flat Cornet

This used to be the gold standard of band instruments.  The brass section was built on a solid section of B-flat Cornets.  Three Cornet parts and two Trumpet parts were the norm.  The Trumpets were the fanfare and dramatic instruments while the Cornets were the melodic and harmonic instruments.  Nowadays, the Cornet is only thought of as an instrument for beginning students.  We have entirely lost this sound from the band.  Even when the piece calls for Cornets, which many, many pieces do, I can count on one finger the times I’ve actually seen real Cornets used.  Continue reading “B-flat Cornet”

E-flat Soprano Cornet

E-flat Soprano Cornet

e-flat cornet

The E-flat Soprano Cornet is a small soprano/sopranino cornet pitched a fourth above the B-flat Cornet.  This instrument has almost never been used in the traditional concert band setting, but is the highest voice in the traditional British brass band.  I also only know of one single instance where the instrument is used in an orchestral setting (Brian’s Gothic Symphony).  This does not mean that it cannot be used in a band; on the contrary, the high brass needs a voice like this that has the flexibility, delicateness, and softness in this register.

Saxhorns

I’ve purposely skirted around the subject of Saxhorns throughout my run of this blog.  Saxhorns are really a complete mess of a family.  Adolphe Sax intended them to be a homogeneous family of valved brass instruments.  However, to say that these instruments are wholly his invention would be false.  All he did was make them uniform and slap his name on the family.

There are usually thought to be 7 members of the family

  1. E-flat Sopranino
  2. B-flat Soprano
  3. E-flat Alto/Tenor
  4. B-flat Tenor/Baritone
  5. B-flat Bass
  6. E-flat Bass/Contrabass
  7. B-flat Contrabass

In addition to this, there are references to a B-flat Piccolo and  E-flat and B-flat Subcontrabasses or Bourdons.

A performance and explanation (in German) of Adolphe Sax’s instruments using original instruments from Sax.

Numbers 1 through 4 can be thought of as one family, while numbers 5 though 7 can be thought of as a second.  Numbers 5, 6, and 7 are the easiest to deal with, so I shall tackle them first.

The Whole-Tube Saxhorns

A whole-tube instrument is a brass instrument that is able to play the fundamental (i.e. pedal) note with ease.  These are usually wide-bore conical instruments.  Today, we call these tubas.  Saxhorns number 5, 6, and 7 are simply nothing more than today’s Euphonium, E-flat Tuba, and B-flat Tuba, which Sax standardized and somewhat perfected.  Numbers 5 and 6 had four valves, while number 7 had only 3.

The Half-Tube Saxhorns

A half-tube instrument is a brass instrument that cannot play its fundamental pitch easily.  Saxhorns 1 through 4 can usually be placed in the half-tube grouping.  These instruments all have three valves.  Numbers 3 and 4 are virtually identical to today’s Alto/Tenor Horn and Baritone Horn.  In fact, in France, these are still sometimes referred to as Saxhorns.  Numbers 1 and 2 are a little trickier.  Some say that they are closer to cornets while others say they are closer to flügelhorns.  The truth is, they are probably somewhere in between cornets and flügelhorns.  A cornet is firmly a half-tube instrument while a flügelhorn is firmly a whole-tube instrument.  Sax’s original instruments probably could play the fundamental, but not easily.  What seems likely is the the early instrument, and most of those made by Sax himself were closer to cornets, while later instruments, notably those by other manufacturers, were closer to flügelhorns.

Over-The-Shoulder Instruments

OTS saxhorns were a purely American take on the instrument.  These became popular during the Civil War when bands would march in front of the troops going in to battle.  These instruments had bells that pointed backward so that the sound pointed towards the marching troops.  There are several modern groups that use these instruments in Civil War reenactments.

Today

Today, the saxhorns are still with us, but mostly under different names.

  1. E-flat Sopranino – E-flat Cornet
  2. B-flat Soprano – B-flat Cornet
  3. E-flat Alto – Alto Horn
  4. B-flat Tenor – Baritone Horn
  5. B-flat Bass – Euphonium
  6. E-flat Bass – E-flat Tuba
  7. B-flat Contrabass – B-flat Tuba

This is the standard make up of 80% of the modern British brass band, something that Adolphe Sax would immediately recognize.  The name Saxhorn has completely fallen out of use – save in one instance…

The French Orchestral Saxhorn

In France, there is still an instrument called simply the Saxhorn.  It is a bass instrument pitched in C a step above the modern Euphonium.  It has a minimum or four valves, though as many as six are common.  This was the standard French tuba for a large part of the 20th Century and the sound that many French composers, including Ravel, had in mind.  Due to the instrument being a whole-tube instrument and having extra valves, it is able to play most of the tuba repertoire despite being the smallest of the bass tuba instruments.
