How long until I can play a song?
Well it depends on the song, but I know what most people mean when they ask that question, they want to play something that sounds like music to them. And while an individual's speed of progress, time spent practising and standards as to what sounds "like music" to them will likely be so dissimilar to the next student as to make the question a fatuous one, I'll try not to give you nothing in answer to it.
6 weeks. I think the average person; if say they practiced an hour a day, preferably in two half hour sessions - morning and evening can very reasonably expect to sound musical in 6 weeks, give or take 2 perhaps.
What styles do you teach?
Well firstly I'd recommend never trusting a guitar teacher who claims to be an authority on all styles, it's far too lofty a claim than they realise I think.
I studied contemporary music, i.e. music of the 20th century hence, but perhaps the best way to answer that question is to mention the musicians who have most influenced me, and I've thus tried my utmost to emulate over the years. I certainly could talk for a very long time about their individual approaches, tricks and idioms:
Turlough O'Carolan, Vivaldi, JS Bach, Mozart, Beethoven, Paganini, Schubert, Blind Blake, Muddy Waters, Charlie Parker, Chet Atkins, Les Paul, Elmore James, Howlin' Wolf, Hubert Sumlin, Scotty Moore, Chuck Berry, Johnny Cash, Eddie Cochran, Freddie King, John Coltrane, The Shadows, Albert Collins, Booker T. & The MG's, Antonio Carlos Jobim, Bob Dylan, Mississippi Fred McDowell, Simon & Garfunkel, The Beatles, Bert Jansch, The Rolling Stones.
They are still my most common go-to jam buddies.
Do I need to bring my own guitar to the lessons?
It's entirely up to you, I have spare guitar at my house for you to use, though you will of course need a guitar to play on at home, but if you're a beginner and unsure about buying your first guitar, I'd recommend renting an instrument. Most music shops these days offer guitar rentals.
Do you teach grades?
Yes, I certainly can do if that's what a student wants. I've taught R.G.T., Rock School and Trinity College London grades in the past based on the student's preferred exam board. However I am accredited by R.G.T. and can procure small discounts off the grade books, etc. But I am quite familiar with the areas of proficiency these various exam boards like to test, and what the examiner's specifically look for. I would definitely recommend choosing an exam board which will reward the graduate with UCAS points, not only is that an indicator that the exam board is a respectable one, but a distinction at grade 8 can get you 75 UCAS points, and is therefore a massive boon to anyone considering going into higher education.
