B Major Scale - A Detailed Guide To The Key Of B Major (2024)

Learning piano scales is about much more than sharpening your technique. Through scales, you can better understand keys and chord progressions. And from there, you’ll be better equipped to improvise and write music. Today, we’ll take a look at the B major scale.

A Quick Introduction to the B Major Scale

B major may not be one of the most common key signatures, but more popular songs than you realize are written in B. The key of B major has been described as being full of color, wild, passionate, and even full of jealousy or anger. Although it’s considered to have an “upbeat” sound like most major keys, B major is quite emotionally complex.

This key isn’t too common in the classical world. Haydn’s Symphony No. 46 is one of the relatively few major symphonies in B major. The “Flower Duet” from the opera Lakmé is also in B.

Structure and Formula of the B Major Scale

You likely already know the formula of whole and half steps you need to follow to devise a major scale. Starting with the root note, you just follow the formula W-W-H-W-W-W-H, where each W indicates a whole step (also called a whole tone) and each H indicates a half step (also called a half tone). When we do this starting at B, we get these seven notes:

How to Play and Learn the B Major Scale on Piano

When mastering any scale on the piano, consistent practice is critically important. Be sure to master the correct fingerings early on! Here’s how o play it with both your right hand and left hand.

Right Hand:

First, find B on the keyboard. It’s the white key to the left of C. Play it with your thumb.
Then play C# (the first black key to the right of B) with your index finger.
Now play D# (the black key to the right of C#) with your middle finger.
Next, cross your thumb under your fingers to play E (the white key to the right of D#).
Then play F# (the first black key to the right of E) with your index finger.
Now play G# (the next black key) with your middle finger.
Next, play A# (the next black key) with your ring finger.
Finally, play B (the white key to the right of A#) with your pinky.

Left Hand:

Start by playing B with your ring finger.
Then play C# with your middle finger.
Next, play D# with your index finger.
Now play E with your thumb.
Next, cross your fingers over your thumb and play F# with your ring finger.
Then play G# with your middle finger.
Now play A# with your index finger.
Finally, play B with your thumb.

As you practice, be sure to use the same fingerings for both ascending and descending scales. Using a metronome can help you master playing in time: start at a slow tempo and gradually increase it. Play one octave at a time, and then add an octave higher as you get more comfortable. This video lesson does a good job of taking you through the scale.

Relative and Parallel Scales

As you learn more piano scales, you’ll start to get a feel for how they relate to one another. One helpful relationship to know is that of relative major and minor scales. Each major scale has a relative minor scale. These relative scales include the same notes (but in a different order). The relative minor scale of B major is G#m (G#-A#-B-C#-D#-E-F#).

Parallel scales share the same first note (or root note). The B minor scale is the parallel scale of the B major scale, as both scales start with B.

Chords of the Scale and Their Scale Degrees

If you want to start writing music in the key of B, it can be helpful to know what chords are in the key. We can figure this out by labeling each of the scale degrees with a Roman numeral using the pattern I-ii-iii-IV-V-vi-vii°. The uppercase numerals stand for major chords, the lowercase ones stand for minor chords, and the “°” symbol indicates a diminished chord.

Using this pattern, we can see that the individual notes of the scale each have a corresponding chord:

I. B major (B)
ii. C# minor (C#m)
iii. D# minor (D#m)
IV. E major (E)
V. F# major (F#)
vi. G# minor (G#m)
vii°. A# diminished (A#dim)

When you know which keys correspond to which Roman numerals, you can quickly and easily transpose any song into the key of B major. This numbering system is called the Nashville Number system, and this video will show you how to use it to transpose music.

The Jason Mraz hit “I’m Yours” uses a I-V-vi-IV (B-F#-G#m-E) progression. “Wannabe” by the Spice Girls follows a V-vi-IV-I (F#-G#m7-E-B) progression. And most of “Ironic” by Alanis Morissette uses a V-vi-V-I (F#-G#m7-F#-B) progression.
