'As well as studying the sciences, Music provided me with a firm artistic background which has helped to inspire me in many walks of life. Whilst at college in Bury, Lancs, I decided that percussion provided a satisfying solution for the practical requirements of the syllabus and very much enjoyed playing not only in the college orchestra in various concerts including Gilbert & Sullivan’s operetta ‘Patience’, but also the then Bury Orchestra, conducted by George Hadjinikos, performing such works as Don Giovanni, The Marriage of Figaro, Bruckner’s 8th Symphony and Mahler’s 4th Symphony.
Between them, the timpani (usually three in number with diameters ranging from 20 to 30 inches) cover a range of around two octaves; each individual drum has a practical range of roughly a fifth. The normal point of impact is about four inches from the edge; when struck too near the edge the sound can be harsh and brittle, whilst the centre of the drum produces an unsatisfactory note of indeterminate pitch. In classical times, wooden sticks were used. Berlioz was the first composer to specify specific types of stick in his scores: wooden, sponge-headed or leather-covered. Over the years, customs have changed and nowadays players usually use felt-covered sticks of varying softness or wooden sticks (or other devices) when specifically demanded by a composer. Unusual requirements include Elgar's Dream of Gerontius in which the composer asks for the handle of the stick to be used rather than the head. Elgar was, in fact, meticulous in his instructions to timpanists. For the thirteenth of his Enigma Variations, two old pennies are traditionally used instead of sticks, to give an impression of the pulse of a ship's engines. [Some years ago, the writer presented Raymond Lomax, then principal timpanist of the BBC Philharmonic, with a pair of old pennies for this specific purpose; they were dated 1899, the year of the work's first performance].
The notation of timpani parts is as delightfully ambiguous and confusing as is the case for most other instruments of the orchestra. In the early days, composers did not even feel it necessary to write out a part for the unfortunate timpanist, requiring him to invent a part for himself as the performance proceeded. In classical times, two timpani was the standard complement, traditionally tuned to the tonic and dominant of the prevailing tonality. Notes wereA further ambiguity relates to the matter of rolls: the rapid alternate use of two sticks on a single drum to give a virtually continuous sound. Some composers (for example, Mozart) indicate this on the timpani part as a trill [c], despite the fact that for every other instrument such an instruction would require two adjacent notes to be played in rapid succession. But to confuse the issue, other composers (such as Haydn) prefer to show a roll as a sequence of semiquavers, demisemiquavers or even hemidemisemiquavers, often with no consistency even within a single work [d]. Beethoven even managed the rare feat of using both notations within a single prestissimo bar at the end of his Fifth Symphony [e]. Exactly what he had in mind is really anyone's guess. As might be expected, Hector Berlioz (himself a timpanist) left nothing to chance, specifying his requirements in absolute detail [f]. It is also typical of Berlioz that he should hold the record for the greatest number of timpani in a standard repertoire composition: eight pairs of timpani played by ten timpanists in his Grande Messe des morts.
