THIS IS A PIECE OF MY BOOK: TENT BOY TENT LIFE

"The “Operation Rudi Nyumbani” was taking course as the lorries popularly known as Tugogo wound their way on the dusty path leading to the strategically located tent areas. Everyone in the Burnt Forest Town tents was busy tying their baggage and luggage preparing to go back to their niche. My most profound pleasure was being given free lifts to the areas I had just been visiting like Rurigi,Kamuyu, Kondoo Center and Bindura. Surprisingly, the tent school we were in closed with immediate effect from Eight a.m. Monday in the first week of June. Ever heard of a school closing at this time of year (except the striking schools)? Well, that was our custom. What you hear being called a school was just big tents, without doors . No teachers no books and nothing. Only tents that could be mistaken for conference halls. And this wasn't healthy for a Form three student like me. But that was how things were. We had already switched to this kind of life since we were flushed out of our homes in 2007. this year when mentioned sends jitters even to small children who witnessed the work done by the arsonists. They are the reason behind us living in tents and not our houses. The ultimate reason why we were suffering.................."

Standard tuning

I FOUND THIS ON WIKIPEDIA AND I THINK IT CAN BE USEFUL Helmholtz notation Note: This article uses Helmholtz pitch notation to define guitar tunings. v · d · e Standard tuning (listen) Notes in standard tuning. Making a standard tuning using overtones Standard tuning is by far the most popular tuning on a 6-string guitar. It consists of the following notes. String Note Frequency Scientific pitch notation 1 (Highest) e' 329.63 Hz E4 2 b 246.94 Hz B3 3 g 196.00 Hz G3 4 d 146.83 Hz D3 5 A 110.00 Hz A2 6 (Lowest) E 82.41 Hz E2 The pitches referred to above are referenced standard pitch (a' = 440.0 Hz.). In some regions of Europe, especially Germany, Serbia and Poland, and in Russia and Ukraine, where classical musicians use the German system, the B natural is indicated with the letter H: in music notation, H is B♮ (B natural) and B is B♭ (B flat). The guitar, as conventionally fretted, is an equal tempered instrument. The guitar is a transposing instrument. In the case of the guitar, its actual pitches sound one octave lower than notated. Letter names in table reflect pitch in Helmholtz pitch notation. This pattern can also be denoted as E-A-d-g-b-e'. (See note for an explanation of the various symbols used in the above table and elsewhere in this article.) Standard tuning has evolved to provide a good compromise between simple fingering for many chords and the ability to play common scales with minimal left hand movement. The separation of the first (e') and second (b) string, as well as the separation between the third (g), fourth (d), fifth (A), and sixth (E) strings by a five-semitone interval (a perfect fourth) allows notes of the chromatic scale to be played with each of the four fingers of the left hand controlling one of the first four frets (index finger on fret 1, little finger on fret 4, etc.). It also yields a symmetry and intelligibility to fingering patterns. The separation of the second (b), and third (g) string is by a four-semitone interval (a major third). Though this breaks the fingering pattern of the chromatic scale and thus the symmetry, it eases the playing of some often-used chords and scales, and it provides more diversity in fingering possibilities. I open 1st fret (index) 2nd fret (middle) 3rd fret (ring) 4th fret (little) 1st string e' f' f♯' g' a♭' 2nd string b c' c♯' d' e♭' 3rd string g a♭ a b♭ ... 4th string d e♭ e f f♯ 5th string A B♭ B c c♯ 6th string E F F♯ G A♭ Chromatic note progression It is important to note that the relative harmonic ratio (e.g. semitones-steps) between neighboring strings, does not change when moving up the frets. For example when considering the 1st and 2nd strings: e' to b (open strings) is like f' to c' (1st fret) is like f♯' to c♯' (2nd fret) etc. The chromatic (equal tempered) musical scale and the natural musical scale have note pitches that are in some instances similar. The natural musical scale uses natural harmonic pitches. For example, the A note has harmonics pitches for the D and E notes. The guitar fretboard can approximately accommodate to tuning to the chromatic or natural musical scale by adjusting the intonation by a little. Intonation is tuning of the fret notes to other fret notes of one string so that most of the fretboard note pitches are tuned to the pitches of the musical scale. Intonation tuning is done by adjusting the string lengths at the bridge. The open string note of a particular string is kept constant so that when adjusting the string length, most of the fretboard pitches are closely matched to the pitches of the musical scale for this string. Tune the open string by adjusting the string tension at the tuning gear using a decent electronic tuner for tuning. Then check the intonation tuning of the fifth, seventh, ninth, twelfth, sixteenth and nineteenth fret note pitches of this string by ear using an electronic chromatic pitch pipe that comes with the above tuner. If these pitches are too high, move the bridge saddle back (away from fretboard) from about 0.5 to about 9 millimetres for the sixth string for a 0.65 metre scale length. If these fret note pitches are too low, then move the bridge saddle forward a little instead. Next tune intonation of other strings each in same way.
