Many of us like shredding in Harmonic and Melodic minor scales as well as the Persian scale (0-1-4-5-7-8-11-12) and it always sounds cool to incorporate exotic, Arabic-ish scales in solos. Unfortunately, standard guitars are unable to accurately reproduce many of the scales employed in Arabic and Mid-East music due to its use of Quarter-steps, and especially the 3/4 step interval (1 and a half frets). There are ways to bend your notes, re-tune your strings, etc, to try and emulate these quarter steps, but there is no comparison to actually having quarter-step frets on your guitar, enabling you to play quarter, half, whole, and 3/4 step intervals. I find it to be more practical as well, and I can still play everything I could normally play on the guitar. I also prefer this to the idea of having a fretless guitar, as fretless instruments are not restricted to quarter-steps and the octave can be divided into far more than 24 notes. Plus fretless guitars do not sound or feel the same as fretted guitars. This guitar has 24 frets to the octave, 48 total. It takes 4 frets to go up a whole step, and there are literally twice as many notes to choose from when writing. All 12 of the notes normally found on a guitar are here, as well as 12 new ones. A fellow SS.org member showed me a website that lists many middle-eastern scales that employ quarter-tones, and out of them I have been concentrating on one in particular, the Huzam, Rahat El Arwah scale in the Maqam family of scales. I don't really know much about the theory behind this scale and the Maqam system, I have been trying to find my own way to use the notes. I gravitate towards this one scale in particular because, with the exception of the root note, all the notes in the scale are located on the extra, quarter-step frets, meaning that this scale just cannot be played on a normal guitar. I wrote this "song" to exemplify this scale, and the approach I applied here can best be approximated to the "modal" way that we approach our western scales. The song uses 4 chords, starting from the root note, then to the 2nd, 3rd, and 4th notes in the scale respectively. The soloing over it plays in the octave starting from the root note and ending on the root note, then goes to starting from the 2nd note and ending on the 2nd note, then the 3rd to 3rd, etc, just like playing modes on a regular guitar. I got lucky and was able to find some sound clips of actual Middle-Eastern music that uses the very same scale as this song, I was able to borrow a couple of pieces of music to incorporate into this song, with just a slight pitch shift to match the natural "B" of my 7 string (the scale actually starts a quarter step below "B", or the note that lies between Bb and B) I put together this diagram of the fretboard showing all the notes and positions for the Huzam, Rahat El Arwah scale on a 7 string quarter-tone guitar, and I used the color Red to highlight the root note of the scale all over the fretboard, in this case "B" These kinds of guitars are hard to play. In fact, the first time I picked one up I could barely manage to pull off a C major scale in the 1st position! It definitely takes a bit of practice and getting used to. For me it is well worth it though, and the use of authentic middle-eastern scales is just one of the many new and exciting things I can do with these 12 new notes, it's a real shame that microtonal guitars haven't really taken off....yet!
