Yes. I sometimes see Bbb in the key signature in wind ensemble work, and there is one well-known instance in symphonic literature. I've forgotten the composition, but IIRC, the bassoon solo on the repetition is really in E major. Notation is an imprecise method of expressing purpose. While it is true that an Ab and a G# are often somewhat different pitches in musical contexts, it is not required to notate them differently. It is the competent professional's responsibility to play them appropriately. (assuming a capable instrument - most wind and string instruments are capable of shading the pitch enough, although keyboards and tuned percussion are not)
Pianists utilize piano fingerings as a guide to rapidly learn music. Scales and arpeggios are both musical elements that composers regularly use in one form or another in their works. Scales and arpeggios are beneficial for improving technical proficiency in an aspiring pianist since they are the building blocks of many compositions. In piano music, numbers are used to symbolize fingers. The numerals below correlate to the corresponding fingers:
2. Descending G-sharp natural minor scale On the keyboard, treble clef, and bass clef, this step illustrates the descending G-sharp natural minor scale.

Names of piano key notes This phase illustrates the white and black note names on a piano keyboard to familiarize yourself with them and to demonstrate that the note names begin to repeat after 12 notes. The white keys are designated by the alphabetic letters A, B, C, D, E, F, and G, a pattern that repeats itself throughout the piano keyboard. Each white or black key may have an accidental designation of flat(b) or sharp(#), depending on how the note is utilized. If sharp or flat notes are used in a subsequent stage, the identical accidental names will be determined. The audio files below play each note depicted on the piano above, so middle C is the second note heard (marked with an orange line at the bottom). Treble Clef Bass Clef
While the key is seldom used in orchestral music except to modulate, it is not commonplace in keyboard music, as in Alexander Scriabin's Piano Sonata No. 2. It is also included in Shostakovich's 8th String Quartet's second movement. If G-sharp minor is used in orchestral music, composers often write B wind instruments in the enharmonic B-flat minor rather than A-sharp minor to make the piece easier to read (or A instruments used instead, giving a transposed key of B minor). Only a few symphonies have been composed in G-sharp minor, including Nikolai Myaskovsky's 17th Symphony, Elliot Goldenthal's Symphony in G-sharp minor (2014), and Marc Blitzstein's abandoned work of juvenilia.
