Here is the trick for finding out which major key you are in when reading a sharp key signature: Find the last sharp. Go up one half-step. This is your major key. On the example above, the last sharp is A#

seven sharps

It is enharmonically equivalent to D-flat major. Its key signature has seven sharps….C-sharp major.

Key signature, in musical notation, the arrangement of sharp or flat signs on particular lines and spaces of a musical staff to indicate that the corresponding notes, in every octave, are to be consistently raised (by sharps) or lowered (by flats) from their natural pitches.

For key signatures with sharps, the key signature is the note name half step above the last sharp. This is the key of G because F# is the last sharp in the key signature.

Jimi Hendrix was famous for this; tuned a half step down. Other reasons; to create a different atmosphere in the music; as in the case of Metal where instruments are down-tuned to create the darkest most aggressive sounding riffs possible.

JIMI HENDRIX AND 432 In some articles Jimi Hendrix is mentioned of using 432Hz. Hendrix, like Marley, used 12-TET guitars. Often musicians have to re-tune their instruments in between pieces during a concert. Changes of temperature and even amount of moisture can detune instruments

On a guitar, a half step is the interval between one fret and the next (while a whole step is two frets). The symbol used for a flat is this symbol: ♭ or a lowercase b. All that to say: E flat (Eb) is one half-step lower than E. It’s also important to note that Eb is the same note as D sharp (D#).

E flat and D sharp is physically the same key but theoretically in music have different positions. If you were to play music in the key of E flat or B flat or D flat and etc, then E flat exists in those keys. D sharp exists in other keys like the key of E or the key of B and etc.

The open sixth string, E, is tuned one half-step lower to E♭ (hence the name “E flat tuning“), the open fifth string, A, is tuned one half-step lower to A♭, and so on with the rest of the strings. Standard Guitar Tuning (starting with the thinnest string, high E)

So you will actually tune the strings to (D#, G#, C#, F#, A#, D#) according to your tuner’s display. You will end up with a more precise tuning if you tune down below the correct pitch and then tune the string up to the correct pitch

Keep it at 440. If A4 is 440hz then the half step down would be Ab4 at 415.3047hz. If that is what you wanted to know. But you can keep it at 440hz and just tune them half step flat

Full Step Down is a tuning where all six strings are tuned down 1 full tone. Your guitar will sound lower and the strings will be looser, but you can still play any song the same way, it will just sound lower.

What you want is a CHROMATIC tuner. Or tune to e standard first then fret the 6th fret and tune the low e to match the a. Then the low e is down a half step then tune the rest of the strings relevant to it. Or tune to e standard first then fret the 6th fret and tune the low e to match the a

A capo can only shift the tuning up, not down. If you want to go down, you can change the tuning on your guitar. For example, to play E shapes and hear Eb shapes, just tune every string down by one semitone. Doing this will reduce the tension of your strings

Drop D tuning is one of the easiest alternate tunings to learn. It changes the pitch of just one string, adjusting the tone of your low E string by a full step, taking it down to a D. This is why many guitarists expand their repertoire to include alternate tunings, branching out from standard tuning.

This movement – from ‘F’ to ‘F#’ – is a half-step up. If we start on ‘F’ and move down in pitch to the next closest note, we are moving right to left from ‘F’ to ‘E. ‘ This movement – from ‘F’ to ‘E’ – is a half-step down.
