Key Of B-Flat or A-Sharp on Guitar: Chord Shapes, Major Scale, Popular Songs in the Key of B-Flat or A-Sharp


A-Sharp Major / B-Flat Major: The Pollyanna of the Music World

The key of B-flat guitar could also known by its enharmonic equivalent, A-sharp, if A-sharp didn’t have a whopping ten sharps. A key has only seven notes, so some of those sharps have to double up; the sixth note, for example, is F##, which actually makes it a G.

Because these double sharps make everything so darned complicated, and because the same key scored as B-flat has only two flats, guess which key signature most composers are going to pick? It’s because of this that A-sharp is referred to as a theoretical key and usually left to collect dust on the shelf.

What could be a happier underdog song than Chuck Berry’s B-flat rocker “Johnny B. Goode?”

A theoretical key is a key that exists in theory but doesn’t get used much because it’s so much easier to just use its enharmonic equivalent; the notes of the scale all sound exactly the same, the key just has a different name and key signature.

The same applies for the chord. If you go to the Uberchord chord finder and type in “A#” you’ll get a chord position and the notes Bb, D, and F. Then type in “Bb” and you’ll get exactly the same chord position and exactly the same three notes.

B-flat major is like Pollyanna, a character created by author Eleonor H. Porter. She always looked on the bright side, turning life’s lemons into lemonade.

Why complicate things? Always follow the KISS rule (Keep It Simple, Stupid) and you can’t go wrong. Today we’re going to follow the KISS rule by showing you the B-flat guitar chord, looking at B-flat’s history and its use in popular music and figuring out how hard it is to play it on the guitar. We’ll also jam through a few of B-flat’s songs and chord progressions.

The key of B-flat major is like that perky girl you know who smiles through life’s tempests, who takes five minutes to get over a breakup, who deals with disappointments by grinning, shrugging, and saying, “Oh well, there’s a brighter world just around the corner.”

The key of Bb guitar was extremely popular among symphony composers of the Baroque, Classical, Romantic and Modern eras in music, but this may have had something to do with the tenor sax, the soprano sax, the clarinet, and the trumpet, all of which instruments are so important in the symphony orchestra, being Bb instruments. Bb just worked. And it still does.

Harold Shapero’s Symphony for Classical Orchestra is filled with sound, fury, passion, tenderness, and good vibrations, all in the key of B-flat major.

The B-Flat Major Chord Position on the Guitar: Moderately Difficult— and Immensely Useful

This basic chord position is one of those great shapes, like the F bar chord position, that can be played all the way up the neck to make a host of other major chords. Holding all the strings down makes it less resonant, and it can be tricky to play it clearly, but that’s when you pull out your trusty Uberchord app and let it point you right. Just set up your smartphone and keep playing the chord (you can even program in chord progressions), letting the app show you how to improve.

Key Of B-Flat Guitar Theory and Practice: The Pattern of the B-Flat Major Scale Explained

The pitches in the key of B-flat major are B♭, C, D, E♭, F, G, and A.


This is the B-flat major scale, with Bb at its root and another Bb, an octave higher, at its zenith. As you can see, the only accidentals are Bb and Eb.

The simple B-flat major chord, which forms the root of the B-flat major scale, contains the notes Bb, D, and F— the first, third, and fifth notes of the key of Bb major. On the guitar, using the basic Bb chord position shown in the diagram above, these notes arrive in this order: Mute, Bb, F, Bb, D, and F.

If bar chords are still tricky for you, you can play just the top four strings of this chord. You can still move this position up the neck, just be sure to keep the two bass strings mute.
