Get in the groove!
When practicing guitar with a metronome, it's helpful to focus on specific rhythmic subdivisions. For example, instead of just playing along with the metronome at a steady tempo, you can divide each beat into smaller units and practice playing in time with those divisions.
One common rhythmic subdivision to practice is eighth notes, where you play two notes for every click of the metronome. So, if the metronome is set to 120 beats per minute (bpm), you would play two notes for each click, for a total of 240 notes per minute.
You can also practice playing sixteenth notes, where you play four notes for every click of the metronome. This can help improve your ability to play fast and intricate rhythms.
Another approach is to practice different rhythmic pattern like triplets, quintuplets, septuplets etc. These patterns helps to increase your flexibility on the instrument and make your playing more interesting.
This approach needent only apply to single note melodies and scalar practice. Try it with chord patterns/strumming patterns too! Much of funk,
hip-hop and more modern urban styles are based around this idea of subdivisions with rhythms.
It is always good to start with a simple pattern and slowly build up the complexity as you get more comfortable. Remember to take your time and be patient with yourself as you work on developing your sense of timing and rhythm.
