An entertaining aspect the holeless nat is the spectacle of a player holding an instrument to his (or her) mouth with just one hand and no finger movement, the other placed casually about their person. Audience members and fellow performers often comment along the lines of : What, you do all that with just your mouth? To which the reply is usually Well, you can sing, cant you? How do you do that? So why isnt everybody doing it?
There are several reasons why we are unable to hear the holeless nat in public. The rarity of its use creates a chicken-and-egg situation for people likely to be inspired to learn it. Most baroque trumpeters are reluctant to learn the holeless nat. In the words of Ray Allen (my modern trumpet teacher at the RAM), when I mentioned learning the natural trumpet, he looked at me with incredulity and said, We have valves now, why make it more difficult for yourself? It requires quite a leap of faith to spend time and money on equipment, lessons and yet more practice. Players may be worried about the possible adverse effects of using such a radically different mouthpiece. It took Madeuf about five years to adjust at the leading edge. I had about five months of hard labour with Madeufs enlightened guidance and a couple of the students at Basel managed it virtually overnight. However difficult this transition seemed, the positive effects on the playing of modern trumpets (and the holed nat) were instant and significant for me.
In mainland Europe (not really applicable yet in the UK), if a trumpeter plays the holeless nat, he tends to be overlooked by fixers as someone who is incapable of playing anything else a bit like saying You can climb a mountain so you cant use the escalator or No holes, no gigs. Although the trumpet profession is different abroad, an underlying prejudice exists. One can understand players wanting to protect their hard-earned work. I have gone to engagements in this country with both trumpets, played with no holes at first in the rehearsal and then offered the conductor a choice. Usually, they are pleasantly surprised and stay with it.
A few British trumpeters already perform without holes. David Staff, mainly with Jonathan Impett, has been playing classical repertoire with Franz Bruggens Orchestra of the 18th Century (based in Holland) for the last 20 or so years (probably the current world record). Crispian Steele- Perkins has performed and recorded some works (including a stunning The Trumpet Shall Sound on the original c.1717 Harris trumpet from the Bate Collection in Oxford), sometimes playing a half-tone slide trumpet. David Hendry also plays some works holeless with the Gabreli Consort. Notably missing is the main baroque clarino repertoire of JS Bach, Handel, Biber etc.
The pure intonation of the natural trumpet has interesting qualities. A major third, (for instance D-F#), will create a resultant D two octaves below. Fifths are the same (lower note) and sixths (A-F#) result in a D
(giving a triad from just 2 notes!) The prominence of these resultant notes from trumpets underlies the power of the sound. Most interesting is the fourth (A-D), giving a D two octaves below the reason why it was considered a consonance 300 years ago and (with modern equal temperament) a dissonance today (Persichetti, 20th Century Harmony).
According to Altenburg (publ. 1795), organs were originally, at times, tuned to the trumpet and other musicians would obviously then adjust to the ambient intonation. Within this trombacentric system, woodwind players had simpler fingering than is required today to adapt to the industry standard Vallotti, which, ironically, was first published in 1779. As late as 1756, in Leopold Mozarts Treatise on the Fundamental Principles of Violin Playing, fiddlers were encouraged to practise pure tuning.
Temperaments, both human and tonal are a challenge in this next exciting stage of performance practice. Despite the ability to bend notes on the holeless nat, it is only possible to an absolute maximum of 45% flat and 15% sharp between partials (according to Dr Murray Campbell, Edinburgh University Accoustic Research Dept.). Trumpetfriendly temperaments are therefore essential. We will become as familiar with hearing them as we are now with the standard use of meantone in 16th & 17th century music. Ensembles will need valuable rehearsal time to adjust to these new parameters, something that the consummate musicianship of professional players will take in its stride. Audiences will need to cast aside expectations and listen with open ears.
The advantage of study at places like the Schola Cantorum is the time available, the presence of like-minded musicians, and the resources available to rehearse in great depth and address these matters. We have many opportunities to perform in mixed-instrument ensembles and it is taken for granted that the trumpets will not use holes. Solutions are found.
There is a Buddhist saying the only constant is change. I find it inspiring that, although we have spent the last 50 years developing historically informed performance, there is still the enthusiasm for progress by searching backwards. String players are beginning to use unwound gut, more original temperaments adopted, and trumpets are sometimes played without holes. Mistakes occur they happen to us all. Strings will break, pegs slip, notes split, reeds clog and voices dry up in the pursuit of the beauty we all love. We cannot let the fear of such mishaps interfere with our intent. Players and ensembles need to embrace the future. Sure, there will be the odd surprising moment that is what makes live music so engaging. If we expected perfection, we would all listen only to machines!
