So I'm reading this book called piano and keyboard all in one for dummies and in the very last measure of this image you can see a 5 (pinky/little finger) is suggested for the B flat since this is key of F.

I think I read that you're not supposed to use thumb or pinky on black notes? Why does author suggest it here?

As a piano player of over 30 years, I can assure you that the pinky finger plays plenty of black keys. Either hand.

Is it common ...?

I want to say yes, but let's have some specific examples.

  • it's less common to use pinky fingers to play major scales which originate on black keys (Bb, Eb, Ab)

  • no pinky finger is used when playing the chromatic scale

  • pinky fingers are less commonly used for trills (and most other ornaments)

All that aside, I have never considered the pinky to be uncommon or under-used. I use both of mine all the time when playing, and certainly on many black keys. As do most other players I should hope.

    Just to reinforce this answer, when playing Mendelssohn Songs Without Words and other similar music, almost the entire melody is played with the fourth and fifth fingers of the right hand, the other right hand fingers being kept fully occupied with the accompaniment. Plenty of black notes there.

    Another point: How else are you supposed to play octaves if not with the fifth finger?

    @Ian Goldby - Apparently, some people's hands are big enough that they can use their thumb and ring finger to play octaves.

    I can think of at least one Beethoven piece (last movement of the Waldstein) where the 4th and 5th fingers are used for an extended trill (mainly because the other fingers are busy doing the melody below them). I think it occurs in several Chopin pieces as well, I'd have to check if black keys are involved... Commented Dec 18, 2019 at 19:21
  • @Dekkadeci I can play a 10th with my left hand and a wide 9th on my right, so I can pretty easily do octaves using my thumb and ring finger.

I think I read that you're not supposed to use thumb or pinky on black notes?

Then you read incorrectly. It may be helpful for absolute beginners when they are first learning, but by the time a beginner can play more than "Twinkle twinkle little star" with one finger, they should have gone past that rule.

For a very obvious counter-example, look at the first movement of Beethoven's Moonlight Sonata, which should be within a player's ability around Grade 3. Moonlight Sonata score image

The very first notes played on the left hand are C#'s an octave apart. In bar 5 we add octave G#'s in the right hand. The entire piece makes substantial use of notes an octave apart in both hands, and there is no practical way to play this except with thumb and little (pinky) finger.

    "no practical way"? 1st and 4th finger... Commented Dec 20, 2019 at 2:00

    @ApollyssupportsMonica You've got longer fingers than me then, especially if you can do the octave-plus-one stretch in bar 8 like that! As an interesting aside, my mum is a piano teacher, and one of her little fingers is shorter than normal, due to a childhood accident. She's a brilliant musician, but she has trouble playing octaves with that hand, and she really can't reach that stretch - she has to "arpeggiate" it. Which of course she can make sound good, because she's so much better. :)

  • @ApollyssupportsMonica Oh, and practicality does also depend on what else you need those fingers to do. Technically you can play the arpeggios and the top "melody" notes with the first four fingers, I guess, but it wouldn't be my choice of fingering.

When there's a choice! It makes a lot of sense to use a longer finger on the further-away-from-you black keys. Easier to reach, surely? Same reason there's a 'rule' about not using thumbs on black keys.

One always has to use a modicum of common sense when sorting fingering on piano. And sometimes, the 'rule' has to be broken for want of compromise. If it's easier, better, more effective to use pinky (or thumb) on a black key, then so be it. If it's easier (etc.) not to, then don't!

  • I agree. This is exactly what I was taught on organ. It definitely has it's uses, but should not be the first option to consider when deciding on a fingering. It greatly depends on the notes missing in the image. When followed by G+Bb for example it makes sense to use the pinky.

When the aim is to play a scale perfectly evenly, the 'long fingers on black keys, short fingers on white' rule makes sense.

In playing pieces, understand the purpose of that rule, but be prepared to break it! Especially when the bit in question ISN'T a fast scalic passage.


I think you want to distinguish fingerings for scale from chords. And chords can be groups into different spacings like less than an octave, full octave, exceeding an octave. The fingerings for those things have different requirements and so one general rule won't really apply to all of them.

While finger 5 on black is avoided for scales that isn't the case for playing chords. Same goes for finger 1 - the thumb. The obvious case is a full octave chord starting and ending on black keys, ex. E flat minor. A normal fingering for that would be fingers 1 and 5 on the E flats. I suppose a large hand could use 1 and 4, but let's not generalize from extreme cases.

About the finger 5 on B flat in the bass from the example: other options like reaching with finger 4 as - 4 2 1 2 - or some kind of cross over like 4 1 2 1 seem less than ideal. Too much effort to reach or cross. For the suggested fingering - 5 2 1 2 - I would consider these two points: 5 on B flat and 1 on G fits with the concept of keeping the short reach fingers (the thumb in this case) on white and by comparison finger 5 can reach farther than the thumb to the black key. Also, if you keep your fingers arched and move in a little toward the fallboard so your fingers are positioned in the middle of the key length (yellow zone in the picture below) it will mitigate the finger reach issues.

  • This is the answer. Other answers do not note that the rule cited in the question makes perfect sense for scales, but does not apply in the example in question because it's not a scale.

There are no rules about which fingers to use on which keys. Fingering notation is a suggestion (unless indicated otherwise), possibly from the composer himself, so it might be extremely valuable. It may also be awkward depending on your comfort level and relative finger strength.

You'll have a very hard time playing more difficult pieces if you could never use your thumb or pinky on a black note! You may even be indicated to use your forearm or foot on the keys if you look into 20th century avant garde composition...

  • As a rather novice musician I'm a bit shocked that the little/pinky finger is used on black keys at all. I have short pinkies and can't reach the white keys with them (at least with any strength), let alone the black (probably why a strong factor it not progressing beyond being a novice). I Don't even use them to type on a keyboard. It makes me curious what the breakdown is by gender and handspan is for the difficulty of various compositions (and how this affects how people adapt or not). Commented Dec 19, 2019 at 16:37

If you are a beginner (which I guess from the fact that you are reading a "for dummies" book), don't forget that the position of your fingers on the white keys should be up close to the end of the black keys, not right at the end of the keys.

So playing B flat or E flat with your left hand pinky should be easy, since there are no other keys that get in the way. The same is true for F sharp and C sharp with your right pinky.

As others have said, you often need to play any black key with the pinky, and also with the thumb.


I know the rule for playing scales using the thumb on the white keys - and not running from a white key played e.g. by the middle finger under leading the thumb to a black key - let's say you play the B major scale then it is clear that the thumb is on B and E and not (1,2,3,1,2,3,4) and not the ring finger (4) on E and the thumb on F# (1,2,3,4,1,2,3)

So, of the rules you are talking about I only use the one for the thumb and only for scales, but not necessarily for chords, triads and arpeggios. (how would you play a F#major arpeggio F#,A#,C#,F#->A#,C#,F#,A# -> C#,F#,A#,C# ->F#,A#,C#,F#???)

About the rule not using the pinky finger for black keys I have never heard, but it makes sense to play in front of the keys and so it makes sens to use the longer finger to play the black keys as they are further behind.

It also make sense to use the pinky finger that it doesn't get spoiled and lazy to stay in form and strong ;)


I've just seen in your example:

It seems to be a Boogie or Blues like pattern in the left hand:

For beginners it might be an advantage to use the same fingering for the F and Bb chords.


When it comes to fingering, it's all down to context. You cannot decide which finger to use for a note without considering the notes before, the simultaneous notes, and the notes after. You may have some preferences, like not using short fingers for black keys, or not using the weak ring and pinkys for fast trills. But, every singe such rule must yield to the context consideration.

In this case, the left hand plays the Bb followed by f and g. The first interval is a fifth, and the fact that a g follows, discourages the use of the thumb for the f. So, playing the Bb with the ring finger and the f with the index finger would force you to spread your fingers quite significantly. Using the pinky allows your hand to remain in a much more relaxed posture. The fact that there is an f and a g following the Bb determines that the pinky is the best choice for the Bb. If there were a c and a d following the Bb, you'd likely use your middle finger instead.
