A chloridometer is a measuring instrument used to determine the concentration of chloride ions (Cl –) in a solution.It uses a process known as coulometric titration or amperostatic coulometry, the accepted electrochemistry reference method to determine the concentration of chloride in biological fluids, including blood serum, blood plasma, urine, sweat, and cerebrospinal fluid.
Free time is a type of musical anti-meter free from musical time and time signature. It is used when a piece of music has no discernible beat. Instead, the rhythm is intuitive and free-flowing. In standard musical notation, there are seven ways in which a piece is indicated to be in free time: There is simply no time signature displayed.
Audio therapy is the clinical use of recorded sound, music, or spoken words, or a combination thereof, recorded on a physical medium such as a compact disc (CD), or a digital file, including those formatted as MP3, which patients or participants play on a suitable device, and to which they listen with intent to experience a subsequent beneficial physiological, psychological, or social effect.
A feedback loop from the bridge amplifier output to the pre-amp input helps to eliminate any remaining contribution from the fundamental frequency. The output from these blocks is measured, typically using an instrumentation amplifier driving an analog or digital meter. The voltage at the meter is due to the harmonic distortion products plus noise.
In music, the terms additive and divisive are used to distinguish two types of both rhythm and meter: . A divisive (or, alternately, multiplicative) rhythm is a rhythm in which a larger period of time is divided into smaller rhythmic units or, conversely, some integer unit is regularly multiplied into larger, equal units.
Music is scored with commercially available notation software. [39] In addition to the digital audio workstations and music notation software, which facilitate the creation of fixed media (material that does not change each time it is performed), software facilitating interactive or generative music continues to emerge.
The Nordoff–Robbins approach to music therapy is a method developed to help children with psychological, physical, or developmental disabilities. [1] It originated from the 17-year collaboration of Paul Nordoff and Clive Robbins, [2] which began in 1958, [3] with early influences from Rudolph Steiner and anthroposophical philosophy and teachings.

In music, metre (British spelling) or meter (American spelling) refers to regularly recurring patterns and accents such as bars and beats. Unlike rhythm , metric onsets are not necessarily sounded, but are nevertheless implied by the performer (or performers) and expected by the listener.
