Bb EXPLAINEDYou may have come across songs using a B flat chord. Having 'Bb' in the tool box, along with the other basic chord sets we have been learning, will allow you to play so many more interesting songs.
B flat is really pretty easy, as it is more or less just like grabbing the neck of the uke using the first 3 fingers. Your first finger covers the first 2 strings at the first fret. Your 2nd and 3rd fingers take a string each on the corresponding frets. (See pics and chord diagrams)
Of course there are many ways to get there! You may find it easier to try this. Notice the 1st finger is on the 1st fret, the 2nd finger is on the 2nd fret and the 3rd finger on the 3rd fret. By rocking your 1st finger over to cover 2 strings you will have a Bb chord. The trick you use to get this (or any chord) is up to you. You need to analyse what your particular problem is.
Bb However, if Bb still holds dread, here is another clue. Quite often you will be playing a Bb following an F chord.
F Start by playing F. Notice your 1st finger only needs to flatten out to cover the 1st and 2nd strings in a mini-barre. At the same time your 2nd finger only has to move across/down to the next string. Your 3rd finger can now be placed on the 3rd fret of the top / G string and you will be playing Bb. Practice playing F to Bb to F to Bb etc at your own pace until you can do it automatically. Everyone will have some chord changes that cause problems.
*Note: Bb can be played by using the 1st finger to barre all 4 strings.
If that feels more comfortable, go for it, but Bb is an important chord to add to your collection. The same shape can be moved up the fret board to give you other chords. For example, play this shape at the 3rd fret and you are playing a 'C' chord. Yes, we already know 'C' with just one finger, but there can be times when this version, or 'inversion' of the chord, works better in a song. Play the same shape at the 5th fret and you are playing another 'inversion' of 'D'. This may sound superfluous, but as you get more skilled, knowing other versions of the basic chords can be useful. Not everyone will get around to needing or using them, but it is worthwhile knowing there is more than one way to play a chord.
