The vocal folds, that are commonly known as vocal chords are very interesting parts of our body. Very often, people don’t realize that they are the most important source of us being able to produce musical sound as we do. As air passes through these cords, they open and close rapidly; this rapid vibration is what allows us to produce sound. They are housed in the larynx, commonly referred to as the “voice box” (which is the Adam's apple for men).
These cords or folds help us with our breathing as we sing too, although the diaphragm is a big part of the equation. For example, when you hold your breath, and open your mouth to sing, no sound comes out. Therefore, this goes to say that it is very important to be careful with training these cords
The contraction of the inspiratory muscles increases the volume of the thoracic cavity causing the pressure within the alveoli to decrease and air to flow into the alveoli. During resting inspiration, the diaphragm, the external intercostals and the parasternal intercostals contract to stimulate inspiration. During forced inspiration the scalene and the sternocleidomastoid muscles contract to further expand the thoracic cavity. The pectoralis minor muscles also play a minor role in forced inspiration. During quiet breathing, relaxation of these muscles causes the volume of the thoracic cavity to decrease, resulting in expiration. During a forced expiration, the compression of the chest cavity is increased by contraction of the internal intercostal muscles and various abdominal

Ariana Grande is one talented singer. The girl has impressed everyone with her spot-on celebrity singing impersonations and has sung with some of the most talented singers still alive today. However, there's still a lot you don't know about this sassy celeb. Here are the top eight most common misconceptions believed about Ariana Grande.
The Helmholtz resonance of a guitar is due to the air at the sound hole oscillating, driven by the springiness of the air inside the body. This is analysed quantitatively in Helmholtz Resonance.
The role of respiration in speech is to provide a column of compressed air so we can produce sounds by pushing it through tightly compacted or nearly closed structures of the vocal tract. We need to be able to breathe in order to speak or else no sound would project and we would be dead without breathing. The compression of air allows us to make three basic sounds that resonate through our vocal tract. It allows us to make sound, phonation, make plosive sounds, sounds that we trap air to build up pressure then release which results in a popping sound, and then a fricative, when we force air through a constricted place which results in a hissing sound.
Briefly stated, the outer ear (or pinna) 'catches' and amplifies sound by funneling it into the ear canal. Interestingly, the outer ear serves only to boost high frequency sound components (1). The resonance provided by the outer ear also serves in amplifying a higher range of frequencies corresponding to the top octave of the piano key board. The air pressure wave travels through the ear canal to ultimately reach and vibrate the timpanic membrane (i.e.-- the eardrum). At this particular juncture, the pressure wave energy of sound is translated into mechanical energy via the middle ear.
Elana Sanguigni April 18, 2016 Honors Music Term Paper. The Wind Ensemble and Concert Band reflect a rich history. The formation of the Concert and Wind Ensemble bands dates back to the Middle Ages and Medieval Times. The Concert Band and Wind Ensemble have evolved over the years, due in part to significant historical events, music combinations, individuals, and progress.
High school gives you the opportunity to explore and engage with different sports or/and extracurricular activities. Many of which are arguably classified as a sport. Show Choir is one that many single out and classify it as an extracurricular activity. Show Choir is a group of people who combine choral singing with dancing, sometimes within the context of a specific idea or storyline. Traveling across the United States gaining trophies and competing for the best spots to calm a champion reputation within their show choir group. So, what intentionally makes up a sport? If you sweat, work out, compete, or maybe condition can be possibly the considerations on what makes up a sport. Show choir has different forms of memorizing moves, motions put
A timpani is one of the percussion instruments that has a definite pitch. They are also struck by a mallet on the surface of the drum, which is made out of calfskin and is stretched over a copper shell.(1) When analyzing the mallets many notice that they are home made. Timpani’s come in all different sizes, which determines the change in the pitch. They can come in sizes such as a thirty-two inch, twenty-nine inch, twenty-sixth inch, twenty-three inch and the smallest is a twenty inch, which is a higher pitch than the larger timpani’s.(2) Some sound characteristics of a timpani might be evaluated by words such as powerful, deep, booming, or hollow. Timpani’s also create their sound by a petal located at the bottom of the
The National Anthem protests surrounding the NFL have brought much separation between the players, league, and the fans. Instead of the sport being an opportunity for fans to get away from politics, players have brought politics right into the game. The protests are a way for players to show their feelings of social issues, but the National Anthem is not the right time to protest. The National Anthem is a piece of American History and a time to show respect to our nation’s colors. With the growing turmoil in today’s world these protests are showing selfishness in the players, breaking apart the bond between fans, but can help the players express their feelings on a national level.
The instrument that will be analysed in this report is the acoustic guitar. An acoustic guitar is any guitar that uses acoustics as a means to transmit the strings vibrational energy to the air to produce a sound. The sound from an acoustic guitar is initiated by the strings. When plucked with the fingers or a plectrum it creates vibrational energy which is then transferred to the soundboard or soundbox. Without the soundboard the string alone would not be able to produce much sound as it would just cut through the air without causing much disturbance, but since the soundboard is large and flat it moves the air easier, this process is called mechanical impedance matching. This increases the systems energy transfer efficiency and produces a much louder sound.
Pursed lip breathing enhances the lungs mechanisms and expiratory breathing, meaning breathing becomes easier for a patient experiencing dyspnea. This is predominantly useful for patients who have diagnosis of lung conditions that make breathing difficult such as chronic obstructive pulmonary disease (COPD). Chronic obstructive pulmonary disease is a preventable and treatable disease characterized by persistent airflow limitation that is usually progressive. (Lewis, 2017) Patients with this disease process have declining lung function and breathing capability. It can make breathing so hard that it decreases the quality of the life for the patient. Pursed-lip breathing provides significant health
The voice is our primary mean of communication and expression. We rarely last more than a few minutes without its use whether it is talking to someone else or humming quietly to ourselves. We can use the voice artistically in many ways. For example, singing carries the rhythm and melody of speech. It creates patterns of pitch, loudness, and duration that tie together syllables, phrases and sentences. We use the voice for survival, emotion, expression, and to reflect our personality. The loss of the voice is a severe curtailment to many professions. It is affected by general body condition which is why we need to consider the location of the larynx and how that organ produces voice. Surprisingly, this complex biological design is mechanical in function. It is mechanical to the point that when it has been excised from a cadaver and mounted on a laboratory bench, the larynx produces sounds resembling normal phonation. (Titze, Principles)
Music-induced hearing loss is associated with many risks. Listening to loud music has been attributed to a vast array of problems. According to Strasser “Noise-induced hearing loss continues to be the most common occupational disease in industrialized countries.” (Strasser, Chiu, Irle, & Wagener, 2008). One reason listening to loud music for an extended period of time puts people at risk for hearing loss is because it causes damage to and even loss of the hair cells in the Organ of Corti that essentially are responsible for the sensation of hearing (Zhao, Manchaiah, French, & Price, 2010). These hair cells will regenerate after some damage b...
The ear is looked upon as a miniature receiver, amplifier and signal-processing system. The structure of the outer ear catching sound waves as they move into the external auditory canal. The sound waves then hit the eardrum and the pressure of the air causes the drum to vibrate back and forth. When the eardrum vibrates its neighbour the malleus then vibrates too. The vibrations are then transmitted from the malleus to the incus and then to the stapes. Together the three bones increase the pressure which in turn pushes the membrane of the oval window in and out. This movement sets up fluid pressure waves in the perilymph of the cochlea. The bulging of the oval window then pushes on the perilymph of the scala vestibuli. From here the pressure waves are transmitted from the scala vestibuli to the scala tympani and then eventually finds its way to the round window. This causes the round window to bulge outward into the middle ear. The scala vestibuli and scala tympani walls are now deformed with the pressure waves and the vestibular membrane is also pushed back and forth creating pressure waves in the endolymph inside the cochlear duct. These waves then causes the membrane to vibrate, which in turn cause the hairs cells of the spiral organ to move against the tectorial membrane. The bending of the stereo cilia produces receptor potentials that in the end lead to the generation of nerve impulses.
