F#
The enharmonic note of Gb is F#
G flat is the enharmonic of F sharp; thumb and three fingers without the pinky on the left hand, and third finger with pinky on the right hand.
The notes that sound the same but are written differently are called enharmonic notes. An example of this is the notes F# (F sharp) and Gb (G flat) – they are played and sound the same but are notated differently.
F# and Gb are enharmonics. They share the same pitch, but have different functions in musical notation. Especially attuned musicians may differentiate F# and Gb particularly when they appear as thirds or fifths of chords, but yes, they are enharmonic equivalents.
F sharp is the enharmonic.
That's a key that only exists in theory and not in practice (called an imaginary key), because it would have more than 7 flats. The key of G minor has 2 flats (Bb and Eb), so then key of G-flat minor would then have 9 flats. (The notes of that imaginary scale would be: Gb, Ab, Bbb, Cb, Db, Ebb, Fb, Gb) The enharmonic equivalent to G-flat is F-sharp, and F-sharp minor has 3 sharps.
F sharp is the enharmonic.
a trumpet, like every other instrument, can produce all the note from Ab-G Ab A Bb B C Db D Eb E F Gb G so a total of 12 notes, not including enharmonic spellings (F#/Gb is an enharmoninc spelling because it is the same note)
A double sharp is the enharmonic of B nature
The enharmonic tone for F is E sharp.
An enharmonic note is a note that has two names but have the same fingering
