Dial tone

A dial tone is a telephony signal sent by a telephone exchange or private branch exchange (PBX) to a terminating device, such as a telephone, when an off-hook condition is detected. It indicates that the exchange is working and is ready to initiate a telephone call. The tone stops when the first dialed digit is recognized. If no digits are forthcoming, the permanent signal procedure is invoked, often eliciting a special information tone and an intercept message.

History

Early telephone exchanges signaled the switchboard operator when a subscriber picked up the telephone handset to make a call. The operator answered requesting the destination of the call. When manual exchanges were replaced with automated switching systems, the exchange generated a tone played to the caller when the telephone set was placed off-hook, indicating that the system was live and a telephone number could be dialed. Each digit was transmitted as it was dialed which caused the switching system to select the desired destination circuit. Modern electronic telephones may store the digits as they are entered, and only switch off-hook to complete the dialing when the subscriber presses a call or talk button.

Dial (band)

Dial is a progressive rock band based in the Netherlands.

History

Dial was founded in late 2003 by Liselotte Hegt, Rommert van der Meer and Kristoffer Gildenlöw. Early on, the band was pure a hobby but after Kristoffer's departure from Swedish prog metal band Pain of Salvation in early 2006, the band headed towards a more serious destiny.

In summer 2006, the band went to Austria to record their debut album Synchronized together with producer Devon Graves (of Deadsoul Tribe and Psychotic Waltz). This album was released in May 2007 through Prog Rock Records (US).

Tone (literature)

Tone is a literary compound of composition, which shows the attitudes toward the subject and toward the audience implied in a literary work. Tone may be formal, informal, intimate, solemn, somber, playful, serious, ironic, condescending, or many other possible attitudes. Works of literature are often conceptualized as having at least one theme, or central question about a topic; how the theme is approached within the work constitutes the work's tone.

Difference between tone and mood

Tone and mood are not the same, although they are frequently confused. The mood of a piece of literature is the feeling or atmosphere created by the work, or, said slightly differently, how the work makes the reader feel. Mood is produced most effectively through the use of setting, theme, voice and tone. while tone is how the author feels about something.

Usage

All pieces of literature, even official documents and technical documents, have some sort of tone. Authors create tone through the use of various other literary elements, such as diction or word choice; syntax, the grammatical arrangement of words in a text for effect; imagery, or vivid appeals to the senses; details, facts that are included or omitted; and figurative language, the comparison of seemingly unrelated things for sub-textual purposes.

Tone (musical instrument)

Tone and sound are terms used by musicians and related professions to refer to the audible characteristics of a player's sound. Tone is the product of all influences on what can be heard by the listener, including the characteristics of the instrument itself, differences in playing technique (e.g. embouchure for woodwind and brass players, fretting technique or use of a slide in stringed instruments, or use of different mallets in percussion), and the physical space in which the instrument is played. In electric and electronic instruments, tone is also affected by the amplifiers, effects, and speakers used by the musician. In recorded music, tone is also influenced by the microphones, signal processors, and recording media used to record, mix, and master the final recording, as well as the listener's audio system.

Stringed instruments

The tone of a stringed instrument is influenced by factors related to construction and player technique. The instrument's shape, particularly of its resonant cavity, as well as the choice of tonewood for the body, neck, and fingerboard, are all major determinants of its tone. The material and age of the strings is also an important factor. Playing technique also influences tone, including subtle differences in the amount of pressure applied with the fretting hand, picking or bowing intensity, use of muting and/or drone techniques.
