In a discussion with a vintage guitar/amp store owner who’s been in
the business for 30 years or so, we were discussing floaters and top
mounted pu’s. I questioned him how, if a pickup is activated by the string
moving in a magnetic field, could floating or top mounted pu’s matter
to the sound of the guitar since the wood doesn’t excite the magnetic
field of the p u. I’m pretty sure it matters but want to know why.

This is what I found out.

The strings pushing down on the bridge cause the top to vibrate with a
particular timbre. The timbre is determined by the strength of certain
partials (mainly I reckon) and other aspects. The partials from the vibrating top
cause (through the air) various partials in the vibrating string to be
reinforced with the same relative strengths. Hence the wave form picked
up by the pick-up will reflect the vibrating wood. That’s how I know
it at least.

Get a month or two of lessons to get you started right.

My instructor, helped my ear training by putting chords on a cassette and had me
figure which ones were played by playing my own guitar and comparing.

Also he insisted, I buy a $20 electronic tuner so that i could stay in tune.

Go to chordie.com and you can find a song you like and change chords to an
simpler hand configuration for you to play.

Memorize the chromatic scale Ab, A,.Bb, B, C, C#, D Eb, E, F , F# G, this is
used in using a capo, for instance play an F chord on the first fret and it is
an F, play it on the second fret and it is an F#, on the 3rd fret , it is a G,
and so on. or play an A chord on the first fret, but maybe for your voice, you
want the chords to sound a small higher in pitch, place the capo on the first
fret, and play an A chord two frets down from the capo, like the capo is the new
artificial top of the guitar, and you are using the same hand configuration for
the A chord, but the sounding, the pitch has been changed to B, one key up in
pitch on the chromatic scale!

Simple chord progressions for many songs.

A = A, D, E brown eyed girl
C= C F G This land is your land
D= D G A Colors, Donovan
E= E A B or B7 blue eyes crying in the rain
G= G C D Happiness is a warm gun

You can interchange any of these keys to play any song in any key, the chords
are in a 1-6-8 position in the chromatic scale, note that if you start with A as
#1, D is #6 and E is # 8,

just as if you start with G as #1, C is # 6 and D is #8!

Grab a harp in the same key you are playing with, tape it to top of your guitar
and play the harp with your guitar. Or grab a harp rack that goes around your
neck. Then explore cross harp, which I reckon is four major keys down from your
guitar key, example, play guitar in A, count down four major keys A B C D, and
play a D harp for a blues sound, playing the 4 hole on the harp(blow)and inhale
on the 5 hole, I don’t play harp well so this is a very simple explanation,
subject to correction by other posters, please!
