Within a beat, a single sixteenth note (semiquaver) can be in first, second, third or fourth place (see exercises 1 - 4 above). These strummed sixteenths appear in the notation with a note head, while the muted sixteenths are marked with a cross.
The following exercises 5 - 14 were formed from all possible combinations of the rhythms 1 - 4. For example, exercise 5 corresponds to the combination of rhythm 1 + 2. These rhythms can be heard with a mouse click on the notation as a drum beat with clapping.
In the video the rhythm guitar plays the whole piece using the chord changes | A7 | C#m7 | . To count the rhythms, the measures are numbered with | 1 e + a | 2 e + a | 3 e + a | 4 e + a | .
The 16th note rhythm exercises are included in the Guitar Lovers Studies PDF or as play along track in the Jamtracks PDF which feature high graphic resolution for printing and integrated sound.
