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.
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 C–C–G–C–E–G tuning uses some of the harmonic sequence (overtones) of the note C. [33] [34] This overtone-series tuning was modified by Mick Ralphs, who used a high C note rather than the high G note for "Can't Get Enough" on Bad Company. Ralphs said, "It needs the open C to have that ring," and "it never really sounds right in ...
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 ...
For example, the octave string of the sixth course of a twelve-string guitar is most commonly string twelve, but in the case of the Rickenbacker 360/12 it is string eleven, because of the unusual standard tuning of this particular (and very important) guitar model. An article that referred particularly to the octave string of this pair and ...
For example, in 19 ET, E ♯ and F ♭ are the same pitch; and in just intonation for C major, C ♯ D are within 8.1 ¢, and so can be tempered to be identical. Many musical instruments are capable of very fine distinctions of pitch, such as the human voice, the trombone, unfretted strings such as the violin, and lutes with tied frets.
