IV-V-I-vi chord progression in C major: 4: Major I–V–vi–IV: I–V–vi–IV chord progression in C: 4: Major I–IV– ♭ VII–IV: I–IV– ♭ VII–IV. 3: Mix. ii–V–I progression: ii–V–I: 3: Major ii–V–I with tritone substitution (♭ II7 instead of V7) ii– ♭ II –I: 3: Major ii-V-I with ♭ III + as dominant ...
Salem–Spencer sets are also called 3-AP-free sequences or progression-free sets. They have also been called non-averaging sets, [ 1 ] [ 2 ] but this term has also been used to denote a set of integers none of which can be obtained as the average of any subset of the other numbers. [ 3 ]
The extremes of the meantone systems encountered in historical practice are the Pythagorean tuning, where the whole tone corresponds to 9:8, i.e. (3:2) 2 / 2 , the mean of the major third (3:2) 4 / 4 , and the fifth (3:2) is not tempered; and the 1 ⁄ 3-comma meantone, where the fifth is tempered to the extent that three ...
But the fifth C-G stays consonant, since only E has been flattened (C-E × E-G = 5/4 × 6/5 = 3/2), and can be used together with C-E to produce a C-major triad (C-E-G). These experiments eventually brought to the creation of a new tuning system , known as quarter-comma meantone , in which the number of major thirds was maximized, and most ...
The holotype slab is roughly 50 × 60 mm, the pileus was measured as 10 millimetres (0.39 in) long, and the stipe was measured to be 34 millimetres (1.3 in) long. [1] The lamellae of Gondwanagaricites were 4.5 millimetres (0.18 in) wide and are broadly attached to a single apex.
0, 1, 3, 6, 2, 7, 13, 20, 12, 21, 11, 22, 10, 23, 9, 24, 8, 25, 43, 62, ... "subtract if possible, otherwise add" : a (0) = 0; for n > 0, a ( n ) = a ( n − 1) − n if that number is positive and not already in the sequence, otherwise a ( n ) = a ( n − 1) + n , whether or not that number is already in the sequence.
The stipe is 4–7 cm (1 + 5 ⁄ 8 – 2 + 3 ⁄ 4 in) high and 1–1.5 cm (3 ⁄ 8 – 5 ⁄ 8 in) thick and slightly swollen at the base, and is whitish with a whitish ring, which is initially attached to the cap. [16] Also known as a partial veil, this is a key identifying feature of the mushroom. [17]
The cap surface is smooth, often cracking with irregular fissures. The gills are gray to black. The stem is 5 to 10 centimetres (2.0 to 3.9 in) tall, 4 mm thick, and slightly swollen at the base. The spores are black, shaped like lemons, smooth, measuring 11 x 8 μm. The entire mushroom quickly bruises blue where it is handled.
