Sixteenth notes are commonly used within a beat in conjunction with eighth notes. The following example demonstrates two common rhythm figures combining sixteenth notes and eighth notes.
Here are some bass lines which make use of these two rhythms.
Here are four more important 16th note figures. Each of these rhythms is played with the right thumb (T). The first one contains a dotted eighth note. Remember that a dot increases the value of a note by half, so the dotted eighth note is worth three quarters of a beat.
This one contains two sixteenth notes and an eighth note. You may find these rhythms difficult at first but they are all important, so stick with it. Use a metronome as you practice them and count out loud as you play. If you are tapping your foot, make sure it taps only on each beat and not in between.
The next two rhythms involve the use of sixteenth note rests. Once again take them slowly at first, count out loud and use a metronome.
