Hi, I have a guitar that produces sound acoustically!
An acoustic guitar is a guitar that produces sound acoustically—by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification (see electric guitar).

Acoustic guitar
An acoustic guitar is a guitar that produces sound acoustically—by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification (see electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings. The main source of sound in an acoustic guitar is the string, which is plucked or strummed with the finger or with a pick. The string vibrates at a necessary frequency and also creates many harmonics at various different frequencies.
Drum kit
A drum kit — also called a drum set, trap set, or simply drums — is a collection of drums and other percussion instruments, typically cymbals, which are set up on stands to be played by a single player, with drumsticks held in both hands, and the feet operating pedals that control the hi-hat cymbal and the beater for the bass drum. A drum kit consists of a mix of drums (categorized classically as membranophones, Hornbostel-Sachs high-level classification 2) and idiophones - most significantly cymbals, but can also include the woodblock and cowbell (classified as Hornbostel-Sachs high-level classification 1).
Recorder (musical instrument)
The recorder is a woodwind musical instrument in the group known as "internal duct flutes"—flutes with a whistle mouthpiece. A recorder can be distinguished from other duct flutes by the presence of thumb-hole for the upper hand and seven finger-holes: three for the upper hand and four for the lower. It is the most prominent duct flute in the western classical tradition. Recorders are made in different sizes with names and compasses roughly corresponding to different vocal ranges. The sizes most commonly in use today are the soprano (aka "descant", lowest note C), alto (aka "treble", lowest note F), tenor (lowest note C) and bass (lowest note F).
Electric ukulele
An electric ukulele is a ukulele which is electrically amplified. If not plugged in, it can still play acoustically. A solid-body electric ukulele produces very little sound acoustically, requiring an amplifier to be heard from more than a few feet away. Some solid-body electric ukuleles have steel strings and active humbucker style or single-coil magnetic pickups, such as the Blue Star Konablaster, Mahalo MEU1/S, RISA, Monkey Wrench, Mark Vinsel, Stagg, and Vorson electric ukuleles, while other electric ukuleles, such as Eleuke ukuleles, are solid-body electric ukuleles with nylon strings and passive pick-ups under the saddle.
Phonograph record
A phonograph record (also known as a gramophone record, especially in British English, or record) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac; starting in the 1950s polyvinyl chloride became common. In recent decades, records have sometimes been called vinyl records, or simply vinyl, although this would exclude most records made until after World War II. The phonograph disc record was the primary medium used for music reproduction until late in the 20th century.
Guitar
The guitar is a fretted musical instrument that usually has six strings. The sound is projected either acoustically, using a hollow wooden or plastic and wood box (for an acoustic guitar), or through electrical amplifier and a speaker (for an electric guitar). It is typically played by strumming or plucking the strings with the fingers, thumb or fingernails of the right hand or with a pick while fretting (or pressing against the frets) the strings with the fingers of the left hand. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning.
Bass amplifier
A bass amplifier or "bass amp" is a musical instrument electronic device that uses electrical power to make lower-pitched instruments such as the bass guitar or double bass loud enough to be heard by the performers and audience. Bass amps typically consist of a preamplifier, tone controls, a power amplifier and one or more loudspeakers ("drivers") in a cabinet. While bass amps share many features with the guitar amplifiers used for electric guitar, such as providing an amplifier with tone and volume controls and a carrying handle, they are distinct from other types of amplification systems, due to the particular challenges associated with low-frequency sound reproduction.

When was guitar invented

Various tribes back in 1600 BC used to amplify some string harmonics
The string causes the soundboard and sound box to vibrate, and as these have their own resonances at certain frequencies, they amplify some string harmonics more strongly than others, hence affecting the timbre produced by the instrument.

String harmonic
A string harmonic is a string instrument technique which uses the nodes of natural harmonics of a musical string to produce high pitched tones of varying timbre and loudness. String harmonics are, "high pitched tones, like a whistle's, are produced when the musician lightly touches certain points on a string." "A flute-like sound produced on a string instrument by lightly touching the string with the finger instead of pressing it down," against the fingerboard (without stopping). A harmonic may be measured by the location of the node pressed. The primary pitch perceived in a harmonic may be estimated using the complement of the inverse (pressing nodes dampens certain harmonics and brings out others, so every harmonic has multiple simultaneous frequencies, but the harmonic is usually heard as the pitch ).
Burntisland Shipbuilding Company
The Burntisland Shipbuilding Company was a shipbuilder and repairer in Burntisland, Fife, Scotland that was founded in 1918. In 1969 it was taken over by Robb-Caledon Shipbuilders, which in turn was nationalised in 1977 as part of British Shipbuilders. In the 1970s the Burntisland yard switched from shipbuilding to prefabricating modules of superstructure for offshore oil platforms, but orders were intermittent and by the 1980s the yard was largely idle. In 1990 new owners returned the yard to production as Burntisland Fabrications or BiFab, resuming the manufacture of superstructure modules for oil platforms.
History of China
Written records of the history of China date from as early as 1500 BC, from the Shang dynasty (c. 1600–1046 BC). Ancient historical texts such as the "Records of the Grand Historian" (c. 100 BC) and the "Bamboo Annals" (296 BC) describe a Xia dynasty (c. 2070–1600 BC) before the Shang, but no writing on a durable medium have survived. The Shang ruled in the Yellow River valley, which is commonly held to be the cradle of Chinese civilization. However, Neolithic civilizations originated at various cultural centers along both the Yellow River and Yangtze River. These Yellow River and Yangtze civilizations arose millennia before the Shang.
Violin
The violin, also known informally as a fiddle, is a wooden string instrument in the violin family. Most violins have a hollow wooden body. It is the smallest and highest-pitched instrument in the family in regular use. Smaller violin-type instruments are known, including the violino piccolo and the kit violin, but these are virtually unused. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers (pizzicato) and by striking the strings with the wooden side of the bow (col legno).
Harmonic
A harmonic is any member of the harmonic series, a divergent infinite series. Its name derives from the concept of overtones, or harmonics in musical instruments: the wavelengths of the overtones of a vibrating string or a column of air (as with a tuba) are derived from the string's (or air column's) fundamental wavelength. Every term of the series (i.e., the higher harmonics) after the first is the "harmonic mean" of the neighboring terms. The phrase "harmonic mean" likewise derives from music. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields.
Horses in warfare
The first use of horses in warfare occurred over 5,000 years ago. The earliest evidence of horses ridden in warfare dates from Eurasia between 4000 and 3000 BC. A Sumerian illustration of warfare from 2500 BC depicts some type of equine pulling wagons. By 1600 BC, improved harness and chariot designs made chariot warfare common throughout the Ancient Near East, and the earliest written training manual for war horses was a guide for training chariot horses written about 1350 BC. As formal cavalry tactics replaced the chariot, so did new training methods, and by 360 BC, the Greek cavalry officer Xenophon had written an extensive treatise on horsemanship.
Ancient history
Ancient history is the aggregate of past events from the beginning of recorded human history and extending as far as the Early Middle Ages or the Postclassical Era. The span of recorded history is roughly 5,000 years, beginning with Sumerian Cuneiform script, the oldest discovered form of coherent writing from the protoliterate period around the 30th century BC. The term classical antiquity is often used to refer to history in the Old World from the beginning of recorded Greek history in 776 BC (First Olympiad). This roughly coincides with the traditional date of the founding of Rome in 753 BC, the beginning of the history of ancient Rome, and the beginning of the Archaic period in Ancient Greece.
