Reference excerpt

The Stylophone is a miniature analog synthesizer played with a stylus. Invented in 1967 by Brian Jarvis, it entered production in 1968 and was manufactured by Dubreq in London. Around three million units were sold during its original production run. Although primarily marketed as a toy, it was also used by musicians such as John Lennon, Kraftwerk and David Bowie. The Stylophone was relaunched in 2007 by the toy company Re: in partnership with Dubreq, and several new models have since been released.

Original models The Stylophone consists of a metal keyboard made from a printed circuit board and is played by touching it with a stylus. Each note on the keyboard is connected to a voltage-controlled oscillator through a different-value resistor, and touching the stylus to the keyboard closes the circuit. The instrument also features a power switch and vibrato control on the front panel beside the keyboard, along with a tuning potentiometer on the rear. The Stylophone was available in standard, bass and treble variants, with cabinet colours used to distinguish them. The standard model was black-and-white, the treble model was white and tuned an octave higher, and the bass model was beige-and-white and tuned an octave lower. The standard version was the most common. There was also a larger version called the 350S, released in 1971. It featured more notes on the keyboard, various voices, a wah-wah effect controlled by moving a hand over a photosensor, and two styluses. In the early 1970s, Dubreq introduced the Stylophone Pianomate, a piano attachment synthesizer released in 1972. It used plunger switches placed behind the keys of an acoustic piano, allowing electronic voices to be added alongside the piano's natural sound. The Pianomate offered three timbres and vibrato, which were controlled through a separate amplifier and pedal. Dubreq also manufactured accessories such as the Stylophone Mini-Amp, a small amplifier released in 1973 for use with Stylophones and other portable instruments. It featured controls for tremolo and tone, as well as dual inputs that provided additional sound-shaping options. In the mid-1970s, a revised model was introduced featuring simulated wood panelling on the speaker grille and a volume control. Production of the Stylophone ceased in 1975. Entertainer Rolf Harris served as the Stylophone's advertising spokesman in the United Kingdom for several years and appeared on many "play-along" records sold by the manufacturer.

2007 revival In October 2007, 28 years after production had ceased, the Stylophone was relaunched by the toy company Re:creation in partnership with Dubreq Ltd. (re‑formed in 2003 by Ben Jarvis, son of the original inventor). The revival model, officially known as the S1 and manufactured in China, was a digital recreation of the original instrument. While closely resembling the 1960s Stylophone, it added a volume control, audio throughput, and two additional sounds. The Bass, Treble, 350S, Pianomate, and Mini-Amp models were not included in the relaunch, having been discontinued decades earlier as part of Dubreq's original product line.

Stylophone Keyring Released in 2007 during Dubreq's relaunch of the Stylophone brand, the Stylophone Keyring is a miniature synthesizer designed as a collectible accessory. It features a small keyboard that can be played with a stylus and includes a chain attachment for use as a keyring. Smaller and simpler than standard Stylophone models, the Keyring retains the instrument's distinctive appearance and electronic sound. It has been promoted as a fan-oriented product and featured during events such as International Synthesizer Day.

Stylophone Beatbox In September 2009, Dubreq released the Stylophone Beatbox, the first Stylophone model designed primarily for percussion. Unlike earlier Stylophones, it features a circular case with a 13‑pad touch‑sensitive keypad instead of the traditional keyboard layout. The Beatbox includes three sound banks (drum, vocal beatbox, and bass), a tempo control, and a basic record-and-loop function for creating and replaying short sequences.

Stylophone S2 In December 2012, Dubreq released the Series 2 Stylophone (S2), a limited-edition analogue synthesizer manufactured in the United Kingdom.

Stylophone Gen X-1 In January 2017, Dubreq released details of the Stylophone Gen X-1 portable analogue synthesizer. The instrument was designed and manufactured by Dubreq. The Gen X-1 includes controls for LFO, analogue delay, a low-pass filter, and envelope settings. It also features sub-octave switches and an input that allows it to be used as an effects unit.

Stylophone GEN R-8 In October 2019, Dubreq released the Stylophone GEN R-8, a limited-edition analogue Stylophone housed in a metal case. The instrument includes features found on more advanced analogue synthesizers, including dual VCOs, a multimode filter, an analogue delay, and a range of modulation options. Larger than standard Stylophone models, it was produced in an initial limited run of 500 units.

Stylophone Analog Sound S1 In July 2020, Dubreq released the Stylophone Analog Sound S1 as a replacement for the 2007 S1. The new model is visually similar to its predecessor but features less rounded corners and omits the auxiliary input. Internally, the digital sampled sounds were replaced with an analogue oscillator based on a 555 timer IC, while the tone selector offers three octave ranges. According to Dubreq, its sound is closer to that of the original 1970s Stylophones.

Stylophone Bowie Limited Edition In September 2021, Dubreq launched a limited-edition version of the Analog S1 as a tribute to David Bowie. The model features an all-white finish, an official Bowie logo moulded into the chromed grille, and a colour-printed booklet containing photographs, interviews, and tablature for a selection of Bowie's songs, including Space Oddity.

Stylophone Beat In October 2023, Dubreq released the Stylophone Beat, the successor to the Stylophone Beatbox. Like its predecessor, it features a record button, a play button, and a circular metal pad. Unlike the Beatbox, however, it has a more box-shaped design, four sound banks (rock, techno, hip hop, and beatbox), and stay-in-time click track and tempo-lock features. It can also record multiple layers of beats and allows individual sounds to be muted during playback.

Worked examples

Example 1 — a first encounter with Stylophone

Start with the simplest possible case. Write down what Stylophone claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Stylophone before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Stylophone ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Stylophone

In research: Stylophone appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Stylophone in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Stylophone is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 introductions, British inventions, Electronic musical instruments, so understanding it makes those chapters shorter.
In everyday life: Look for Stylophone outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
