In triode datasheets, characteristics linking the anode current (I a) to anode voltage (V a) and grid voltage (V g) are usually given. From here, a circuit designer can choose the operating point of the particular triode. Then the output voltage and amplification of the triode can be evaluated graphically by drawing a load line on the graph.
In music, a trio (from the Italian) is any of the following: a composition for three performers or three musical parts; in larger works, the middle section of a ternary form (so named because of the 17th-century practice of scoring the contrasting second or middle dance appearing between two statements of a principal dance for three instruments)
In music, form refers to the structure of a musical composition or performance.In his book, Worlds of Music, Jeff Todd Titon suggests that a number of organizational elements may determine the formal structure of a piece of music, such as "the arrangement of musical units of rhythm, melody, and/or harmony that show repetition or variation, the arrangement of the instruments (as in the order of ...
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
In music, a triad is a set of three notes (or "pitch classes") that can be stacked vertically in thirds. [1] Triads are the most common chords in Western music. When stacked in thirds, notes produce triads. The triad's members, from lowest-pitched tone to highest, are called: [1] the root. Note: Inversion does not change the root. (The third or ...
Within classical European music, the Song and Trio form is often referred as Compound Ternary form. This is where one of the Ternary form sections can be subdivided into two subsections such as: I-II-I or A-B1-B2-A.
The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode. The control grid usually consists of a cylindrical screen or helix of fine wire surrounding the cathode, and is surrounded in turn by ...
Baroque opera arias and a considerable number of baroque sacred music arias was dominated by the Da capo aria which were in the ABA form. A frequent model of the form began with a long A section in a major key, a short B section in a relative minor key mildly developing the thematic material of the A section and then a repetition of the A section.
