The open-string notes form a C major chord, which is the triad (C,E,G) having the root note C, the major third (C,E), and the perfect fifth (C,G). When the guitar is strummed without fretting even one string, a C-major chord is sounded. By barring all of the strings for one fret (from one to eleven), one finger suffices to fret the other eleven ...
Helicity is a pseudo-scalar quantity: it changes sign under change from a right-handed to a left-handed frame of reference; it can be considered as a measure of the handedness (or chirality) of the flow. Helicity is one of the four known integral invariants of the Euler equations; the other three are energy, momentum and angular momentum.
An open C tuning. Open C tuning is an open tuning for guitar. The open-string notes form a C major chord, which is the triad (C,E,G) having the root note C, the major third (C,E), and the perfect fifth (C,G). When the guitar is strummed without fretting any strings, a C-major chord is sounded.
C tuning. C tuning is a type of guitar tuning. The strings of the guitar are tuned two whole steps lower than standard tuning. The resulting notes can be described most commonly as C-F-A♯-D♯-G-C or C-F-B♭-E♭-G-C. This is not to be confused with C ♯ tuning, which is one and one half steps lower than standard tuning.
The helicity of a particle is positive (" right-handed") if the direction of its spin is the same as the direction of its motion and negative ("left-handed") if opposite. Helicity is conserved. [1] That is, the helicity commutes with the Hamiltonian, and thus, in the absence of external forces, is time-invariant. It is also rotationally ...
In a song in C major, if a composer treats another key as the tonic (for example, the ii chord, D minor) for a short period by alternating between A7 (the notes A, C#, E and G) and D minor, and then returns to the tonic (C major), this is a tonicization of the key of D minor. However, if a song in C major shifts to the key of D minor and stays ...
Dp stands for Dominant-parallel. The word "parallel" in German has the meaning of "relative" in English. G major and E minor are called parallel keys. The G major chord and the E minor chord in the key of C major are called parallel chords in the Riemann system. —
In fluid dynamics, the enstrophy can be interpreted as another type of potential density; or, more concretely, the quantity directly related to the kinetic energy in the flow model that corresponds to dissipation effects in the fluid.
