Duet

Duet (pronounced doo-et or dyoo-et (non-U))

(1) In music, a composition for two voices or instruments.

(2) An action or activity performed by a pair of closely connected individuals.

(3) A pair or couple, especially one that is harmonious or elegant.

1730–1740: From the Italian duet (a short musical composition for two voices), from duo (two) and a diminutive of the earlier duett & duetto, the construct being du(o) (duet) + -etto (from the Late Latin -ittum, accusative singular of –ittus, an alternative suffix used to form melioratives, diminutives, and hypocoristics).  The ultimate source was the Proto-Italic duō, from the primitive Indo-European dwóh.  The French adopted duet before the English in 1740 although the noun may have been used in English from circa 1724; as a verb (to perform a duet), use was first noted in 1822.  The technical form duettino (short, unpretentious duet) emerged by 1839.  Duet is a noun & verb, duetting & duetted are verbs and duettist is a noun; the noun plural is duets.

Madam Butterfly

One of opera’s most memorable duets is the long and rapturous love aria in Giacomo Puccini's (1858–1924) Madama Butterfly (1905).  Among the most performed works in the canon, a number are available on disc, the most radiant surely Herbert von Karajan's (1908–1989) 1974 recording for Decca (Decca 417 577-2DH3).  The lustre of the cast Karajan assembled to perform with the Vienna Philharmonic Orchestra and State Opera Chorus has not since been matched; with Mirella Freni (1935-2020) as Butterfly, Luciano Pavarotti (1935–2007) as Pinkerton and Christa Ludwig (1928–2021) as Suzuki, expectations were high but Karajan conducted a lush high-drama which disappointed few.  Freni was of course a standout but Pavarotti, though not yet the superstar he would soon become, was at his peak and took to the role in a way that influences tenors to this day; Ludwig’s Suzuki remains unsurpassed in its style and by then, Karajan had been forgiven for everything.

Although Maria Callas (1923-1977) seemed even then an improbable Butterfly, her 1955 appearance at La Scala (Warner B00NMQTE4C) must have been extraordinary but, because of the mono technology of the age and some unsympathetic cutting, the recording can only hint at the power and passion of what critics at the time hailed a classic performance; Callas at her brilliant best, diction of cut crystal.  She may never have been the most refined of sopranos but she brought to her roles a thrilling intensity; just as other singers have delivered a more technically accomplished Lucia di Lammermoor, it’s Callas’ version all remember because it was spine-chilling and her Butterfly is similarly unique.

1969 Alfa Romeo Spider Veloce (the Duetto) with coda lunga (round tail).

Although The Alfa Romeo (type 105/115) Spider was continuous production between 1966-1993, it was only during the first three years the bodywork featured the memorable Osso di Seppia (round-tail, literally “cuttlefish”) coachwork.  After 1970, the Spider gained a Kamm tail which increased luggage capacity and presumably also conferred some aerodynamic advantage but purists have always coveted the cigar-shaped original.  One often misunderstood aspect of the Kamm tail is that the aerodynamic benefits are realized only if the flat, vertical surface created was no more than about 50% of the total area of the vehicle (as viewed directly from the back).  That’s why even designs which don’t conform to the requirements are often casually referred to as “Kamm tails”.

The Kamm tail (also known as the Kammback) was named after German engineer & aerodynamicist Professor Wunibald Kamm (1893–1966) who during the 1930s pioneered the shape, his work assisted greatly by some chicanery within the Nazi military-industrial complex which enabled the FKFA (Forschungsinstituts für Kraftfahrwesen und Fahrzeugmotoren Stuttgart (Research Institute of Automotive Engineering and Vehicle Engines Stuttgart) institute he established in 1930s to secure funding to construct a full-sized wind tunnel equipped with a two-part steel treadmill in the floor and an 8.8 metre (350 inch) diameter axial fan, able to drive air at up to 400 km/h (250 mph).  What the two concentric floor turntables allowed was that as well as enabling turbulence to be studied from the side on the running steel belt, but slip angles were also possible.   At the time, it was the most modern structure of its kind on the planet and its very existence was owed to the priority afforded by the Nazis to re-armament, especially the development of modern airframes, most of the money eventually coming from the Reichs-Luftfahrt-Ministerium (RLM, the State Air Ministry).

While Professor’s Kamm’s work on automobile shapes continued, increasingly the facility became focused on military contracts, contributing to the extraordinary range of novel aircraft designs, some revolutionary and most of which would never reach production.  All of this ceased in July 1944 when the facility was severely damaged in air-raids by Royal Air Force (RAF) Bomber Command, a costly campaign which one mission incurred a loss-ration of 20% and it wasn’t until the late 1940s that reconstruction began after it was acquired by Daimler-Benz AG which enlarged and modernized the machinery, the early fruits including the 300 SL (the W194, first gullwing coupé) which won the 1952 Le Mans 24 hour race and the W196R “streamliner” Grand Prix race cars which created such a sensation in 1954.  Although he wasn’t part of “Operation Paperclip” (the US project which secured (by various means including the military “smuggling” them into the country despite many being wanted by those investigating war crimes and crimes against humanity) Professor Kann was acknowledged as one of the world’s leading authorities on turbulence and between 1947-1953 was part of the team working at Wright-Patterson Air Force Base in Dayton, Ohio.  Some of what was undertaken then remains classified but it can be assumed it was all related to military projects and what would later become the space program.

Alfa Romeo in 1965 conducted a competition to find a suitable name for the little roadster and in those days that meant running advertisements in newspapers (which people actually paid for and read) to which readers responded by cutting out and filling in the coupon, writing in their suggestion, putting it in an envelope on which they wrote the address, buying and affixing a stamp and putting envelope in mailbox.  The winning entry was "Duetto" which Alfa Romeo's directors liked because it summed up the romantic essence of a machine definitely built for a couple.  Unfortunately, for some tiresome legal reason relating to an existing trademark, it couldn't officially be used but for decades, among the cognoscenti, it's always been called the Duetto.

To keep the tiresome lawyers at bay, when released at the Geneva Motor Show in March 1966, the car was known as the Spider 1600, the advertising making clear it was intended to be a practical sports car, usable year-round rather than something intended for competition.  Among those who like to call them Duettos, there’s a sub-set of pedants who like to point out that while all Duettos are round-tails, not all round-tails are Duettos because in 1967, Alfa Romeo introduced the more powerful 1750 Spider Veloce and the less potent 1300 Junior, the former positioned a notch above the original, the latter one below.  That’s too nerdy for most who prefer to form factions based upon the tail treatment and surprisingly perhaps, many do seem to prefer the appearance of the abbreviated Kamm-tail and, again surprisingly, that included even the editors of the US magazine Road & Track (R&T), a publication in the 1960s inclined to see anything Italian through a rose-tint, called the coda lunga (round tail) “a contrived design with meaningless styling gimmicks.”  Probably much of the appeal of the original is as a period piece in the same way the exaggerated fins on the early Sunbeam Alpines have some allure although few would claim their pruning didn’t improve the look.
