Accordion

Finzi accordions are manufactured in Italy. The brand is known for its high-quality craftsmanship and attention to detail, typical of traditional Italian accordion makers. These instruments are often sought after by musicians for their rich sound and durability.

Sharon Shannon primarily plays the diatonic button accordion, which is well-suited for traditional Irish music. Her performances often showcase the instrument's expressive capabilities and its ability to blend seamlessly with various musical styles. Shannon is known for her virtuosic playing and innovative approach to the accordion.

Ramon Ayala is known for using a Hohner accordion, specifically the Hohner Corona II model. This type of accordion is popular among Norteño and Tejano musicians for its bright sound and durability. The Hohner Corona II features a compact design with a double-row diatonic button layout, making it ideal for playing traditional Mexican music.

Can't be answered without knowing who made it, all markings, box, papers, accessories, caliber/gauge, long gun or hand gun, finish, condition, etc..

Approoximately $200 to $400, depending on condition.

P Wave

The type of seismic waves that arrive at the surface first and move by compressing and expanding the ground like an accordion are called primary (P-waves) or compressional waves. They are the fastest seismic waves and can travel through solids, liquids, and gases.

An accordion folded filter paper provides more surface area for the filtration process compared to a conical folded filter paper. This increased surface area allows for better contact between the filter paper and the substances being filtered, leading to more efficient separation. Additionally, the accordion folds help prevent clogging and improve the flow of the filtrate.

Sound in an accordion is produced by air passing through reeds when the player compresses or expands the bellows. The reeds vibrate, creating sound waves that are amplified by the accordion's casing. The pitch and volume of the sound can be adjusted by the player's control of the bellows and keys.

Seismic waves, specifically compressional or primary waves (P-waves), move by compressing and expanding the ground like an accordion. These waves are generated by earthquakes and travel through the Earth's interior.

The reed vibrates to produce sound in an accordion. The reed is a thin strip of metal or plastic that is fastened at one end and free to vibrate at the other. When air passes over the reed, it causes it to vibrate and produce the sound characteristic of the accordion.

The main components to every piano accordion are the treble keyboard, bellows and bass keyboard. The treble keyboard is similar to a piano or organ and the keys are arranged at right angles to the musical instrument with the tops of the keys pointing inwards towards the bellows. The bellows is located between the treble and bass ends and its main function is to drive air through the tone chamber to excite the reeds producing sound. The left hand side consists of a Stradella bass mechanism which is standard for all piano accordions.

A piano accordion is considered a wind instrument because it produces sound by vibrating reeds through the passage of air, which is created by the bellows being compressed or expanded. Despite having a piano-style keyboard, the sound generation mechanism classifies it as a wind instrument.

Inside the accordion are reeds. These reeds are usually made of steel and are placed in a wooden frame. When you blow air over the reed, it vibrates and produces a sound. Each reed is connected to one of the keys on the accordion so that the reeds are covered unless you press a key. When you press down a key, that reed is able to vibrate and sound. The bellows are important because they are the source of air. By moving the bellows in and out, you move air over the reeds.

In an accordion the sound is produced by metal reeds vibrating freely (not beating against a frame) when blown by bellows operated by the player. Valves operated by the keys and buttons direct air from the bellows past the reeds, making them vibrate. An accordion is classified as a FREE-REED instrument, along with the harmonica, harmonium, concertina, melodian, melodica and various traditional East Asian instruments such as the Sheng and Sho, whence the accordion and its ilk were originally derived.

A longitudinal wave, such as sound waves, compresses and rarefies like an accordion as it travels through a medium. This compression and rarefaction of particles create areas of high and low pressure, leading to the wave-like behavior of longitudinal waves.

The type of seismic wave that arrives at the surface first and moves by compressing and expanding the ground like an accordion is called a primary wave or P-wave. P-waves are the fastest seismic waves and are capable of traveling through solids, liquids, and gases.

When an accordion is played with no pressure on the buttons or keys, it can still produce sound due to the free reeds inside the instrument. These reeds vibrate when air is passed through them, creating a sound even when no specific note is being played. This unintentional sound is often referred to as the "air button sound."

To make a sound on the accordion the bellows must be operated by pushing or pulling to create a flow of air through valves which house reeds. By depressing a piano key on the right hand or a button on the left hand the valve is opened thereby allowing air to vibrate the selected reed and producing sound. More pressure on the bellows increases the volume of the note & vice versa. There are usually many banks of reeds and by selecting different registers (known as couplers) a great variety of tones can be produced.

The fastest waves that compress and expand the ground like an accordion are primary waves (P-waves). These seismic waves are the first to arrive after an earthquake and travel through solids, liquids, and gases. They cause particles in the ground to move in the same direction as the wave itself, resulting in the compressional and expansion effects.
