The simple strumming pattern on the bottom tab line is meant to reinforce the
importance of a steady beat. While it’s okay to play just the way that it is written, it will sound better if you will substitute more advanced strums as your playing
The chord diagrams above the bottom line of tab shows the chords that you
should be holding with your left hand. Hold the chord that is called for until a different chord is indicated. Notice also that the fret numbers where you are
holding the chords are also written into the tab.
Sometimes there will be fret numbers in the tab that are different than those in
the chord diagram written above it. When that happens you should still hold the chord but modify it to conform to the tab.
The “B” stands for brush and it shows you the direction that you should be
strumming. Notice that the arrow goes in an upward direction you are actually strumming down, since the uke is held with the 1st string at the bottom and the
4th string at the top and the first line of tab is the 1st string.
