Music Express

Music Express is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Music Express rather than just read about it. In short: A Music Express is an amusement ride based on the original Caterpillar rides. Several near-identical ride designs are also produced by other companies: Musik Express by Italian company Bertazzon and US Majestic Rides, Himalaya by American company Wisdom Rides, German company Mack, and French company Reverchon, and Silver Streak by Wisdom Rides.

Key takeaways

Music Express belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Music Express to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Music Express from memory before moving on to harder problems.

Reference excerpt

A Music Express is an amusement ride based on the original Caterpillar rides. Several near-identical ride designs are also produced by other companies: Musik Express by Italian company Bertazzon and US Majestic Rides, Himalaya by American company Wisdom Rides, German company Mack, and French company Reverchon, and Silver Streak by Wisdom Rides. This ride is a modern adaptation of the famous Harry Traver Caterpillar rides.

Design and operation

The ride features twenty 3-passenger cars connected in a circle. These cars rotate on a track with alternating sloped and flat sections. Rotation is possible in both a backward and forward direction, as the ride is manually operated. The ride is powered by 4 DC motors, and can reach a maximum speed of 12 revolutions per minute. (Certain older models have a hydraulic tire/rim drive and they have a tendency to go faster). The riders in each car are restrained by a single solid lap bar that is locked across the body of the car, making the ride unsuitable for young children or people of short stature. The bar must be manually locked or unlocked, and only locks in one position. Lights and music are also controlled by the operator, which (as the name suggests) contribute heavily to the ride experience. After a certain amount of rotations or minutes, the ride operator will be alerted by the control box that the speed is going to increase, usually by a light on the box. At that time the operator will speak on a microphone asking the riders if they would like to go faster. Sometimes the ride operator can do this earlier than the alert light to build suspense. After a minute or two of faster speed, the ride will then slow down, and the operator can then ask the riders if they would like to go backwards. The speed up element is then repeated again only done in reverse. Most parks and carnivals require riders to be at least 42 inches or even taller, depending on circumstances and ride design. Most Music Expresses are built with a backdrop dividing the rear third of the ride from the front two-thirds. This backdrop, normally covered in artwork and lights, provides a mild headchopper-like effect as the riders enter and exit the rear section. As this blocks lines of sight, additional staff are required to safely supervise this ride in operation. More common in Europe than the US, some Music Express rides have a canopy that the operator can use to cover the ride while in operation, very much like the old caterpillar rides. At Kennywood Park's and Dorney Park & Wildwater Kingdom's Musik Express, written above are the words "Mit Musik Geht Alles Besser", which translated from German reads, "With Music Everything Goes Better." The variant used in fairs across Hawaii feature murals of several famous artists, such as the Beatles, Jimi Hendrix, Janis Joplin, Elvis Presley, the logo of the Rolling Stones, and even fictional bands and singers.

Variations

Bertazzon Musik Express No major variations from Mack Rides version. Majestic Manufacturing Musik Express 14 cars, hydraulic locking system, increased top RPM. Wisdom Rides Himalaya 22 cars. Mack Rides Himalaya Music Express, Diskothek Reverchon Himalaya Original Himalaya ride design. Wisdom Rides Silver Streak 16 cars, smaller height difference, multiple lap bar positions. SDC Amor Express Billed as "The Love Machine", circa late 70s, with hydraulic drive and canopy, very much like the original caterpillar rides. Not many found in US anymore but they still can be found in European fair circuits and parks.

Worked examples

Example 1 — a first encounter with Music Express

Start with the simplest possible case. Write down what Music Express 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 Music Express 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 Music Express 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 Music Express

In research: Music Express 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 Music Express 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: Music Express is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amusement rides, so understanding it makes those chapters shorter.
In everyday life: Look for Music Express 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.

Frequently asked questions

What is Music Express in simple terms?

Why does Music Express matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Music Express?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
