Watch the Swing Eighths online guitar lesson by Brad Carlton from Guitar Lab: Shuffle Secrets
Swing eighth notes differ from straight eights in that there is a lope in their sound. This is because the time values of each eighth note are different. In the previous lesson you learned how to count and hear eighth note triplets. To understand swing or shuffle eighth notes, simply tie the first two eighth notes together. What this then creates is a situation where the first eighth note rings two thirds of a beat and the second eighth note rings one third of a beat. To count these all you have to do is delete the syllable “trip”. It would sound like this: 1 (trip) let 2 (trip) let 3 (trip) let 4 (trip) let. As you can see you want to maintain the proper timing by either whispering or leaving space for the syllable”trip” (the second third of each beat). What's important to remember is that you are playing within a rhythmic grid work which consists of three time slots for each beat and 12 time slots for the entire measure.
You will receive a drum groove track which will establish this rhythmic concept. Spend time counting and playing along with the track so you are rock solid in your understanding of this rhythm.
