Major-chord progressions are constructed in the harmonization of major scales in triads.[21] For example, stacking the C-major scale with thirds creates a chord progression, which is traditionally enumerated with the Roman numerals I, ii, iii, IV, V, vi, viio; its sub-progression C-F-G (I-IV-V) is used in popular music,[22] as already discussed. Further chords are constructed by stacking additional thirds. Stacking the dominant major-triad with a minor third creates the dominant seventh chord, which shall be discussed after minor chords.
For example, if the note E (the open sixth string) is played over the A minor chord, then the chord would be [0 0 2 2 1 0]. This has the note E as its lowest tone instead of A. It is often written as Am/E, where the letter following the slash indicates the new bass note. However, in popular music it is usual to play inverted chords on the guitar when they are not part of the harmony, since the bass guitar can play the root pitch.
In an acoustic instrument, the body of the guitar is a major determinant of the overall sound quality. The guitar top, or soundboard, is a finely crafted and engineered element made of tonewoods such as spruce and red cedar. This thin piece of wood, often only 2 or 3 mm thick, is strengthened by differing types of internal bracing. Many luthiers consider the top the dominant factor in determining the sound quality. The majority of the instrument's sound is heard through the vibration of the guitar top as the energy of the vibrating strings is transferred to it. The body of an acoustic guitar has a sound hole through which sound projects. The sound hole is usually a round hole in the top of the guitar under the strings. Air inside the body vibrates as the guitar top and body is vibrated by the strings, and the response of the air cavity at different frequencies is characterized, like the rest of the guitar body, by a number of resonance modes at which it responds more strongly.
Unlike the piano, the guitar has the same notes on different strings. Consequently, guitar players often double notes in chord, so increasing the volume of sound. Doubled notes also changes the chordal timbre: Having different "string widths, tensions and tunings, the doubled notes reinforce each other, like the doubled strings of a twelve-string guitar add chorusing and depth".[38] Notes can be doubled at identical pitches or in different octaves. For triadic chords, doubling the third interval, which is either a major third or a minor third, clarifies whether the chord is major or minor.[39]
UPDATE: SEPTEMBER 3rd, 2010 -- Good evening, and hi everybody! I get requests to add tabs once in a while, and for years one of the most common requests has been 'Psychic Hearts', and more recently 'Trees Outside the Academy'. I resisted for years, but boredom and the need to please has a funny way of making things happen, so I'm proud to bring you tabs for the entirety of "Psychic Hearts" and its related tracks, as well as the majority of "Trees Outside the Academy". I was originally planning on providing bass tabs as well as the Mascis solos, but I decided I wasn't that desperate for accolade. With all this attention on Thurston, I felt bad for Lee, so I've updated my outdated tab for his excellent solo acoustic piece "Here" (located under "Other Tabs") with the proper tuning, which also happens to be the tuning for the equally excellent "Lee #2", so I've updated that one too!
