Being good at recognising a tune and having rhythm is linked to higher nonverbal intelligence, psychologists have discovered.
It doesn’t matter whether or not people have had musical training — musical aptitude is still linked to higher IQ.
People with an aptitude for music are more likely to study it and improve their skills even further, which further enhances their IQ
The conclusions come from a study of 133 people, around half of whom had had musical training.
Many studies have already linked musical skill to higher IQ, the authors write:
“Musically trained children and adults score higher on intelligence tests than their untrained counterparts. Moreover, as duration of training increases,
so does intelligence.”
However, this study wanted to see what comes first.
All were given tests of both melody and rhythm.
The melody test involved listening to short tunes and judging whether they were the same or different.
The rhythm test was something similar, except with beats rather than notes.
The results showed that people with more musical ability had higher intelligence, even when musical training was taken into account.
So,the link between being musical and a higher IQ is down to both an aptitude for music and training.
At its root, the link between music and IQ is partly genetic, the authors write:
“…both music aptitude and intelligence have significant genetic components that overlap to an extent. The specific genotypic structures of general intelligence and music aptitude are not well understood, but it is clear that intelligence is substantially heritable, and that the impact of genetic factors increases from childhood (heritability ≈50%) to adulthood (≈80%)”
The study was published in the journal Intelligence (Swaminathan et al., 2017).
What is a 256 note called?
In music, a two hundred fifty-sixth note (or occasionally demisemihemidemisemiquaver) is a note played for 1⁄256 of the duration of a whole note....
C7 is the diatonic seventh chord built on a root which is the dominant scale degree of F major. The chord is named for the scale degree of its root within a diatonic major scale.
It is so called because B♭ is the 7th note of the C dominant scale (also known as the Mixolydian scale).
The 5th is known as the dominant, because it is the "most important" interval (among other things, it's the first harmonic other than the octave).
However, try to forget the "English" meaning of the word "dominant" -- otherwise you might expect C to be the "dominant" of C. It's not. In C, C is the "tonic". G, the 5th is the "dominant". Other intervals have names like "subdominant" (4th) and "mediant" (3rd) , which at least don't confuse you by having instinctive meanings.
5th relative to C is G. So since the C major scale is C,D,E,F,G,A,B, then the G dominant scale is G,A,B,C,D,E,F
... and the chord of G dominant 7th is the triad plus the 7th from that scale - G,B,D,F
The C dominant scale contains the same notes as F major, since C is F's 5th:
F major: F,G,A,B♭,C,D,E
C dominant: C,D,E,F,G,A,B♭.
So the chord of C dominant 7th is C,E,G,B♭.
Since in most Western music, major is the "default" scale, we might expect "C7" to denote C major 7th - C,E,G,B.
However in pop/rock/etc., the major 7th is relatively rare, and dominant 7ths are very common. Hence people organically settled on the convention of using "C7" to denote the dominant 7th and "Cmaj7" to denote a major 7th.
