This fall I switched back to standard 4ths tuning on my bass guitars. I had been playing bass guitar tuned in 5ths (an octave lower than cello) for the last 7 years!! So it’s been a totally mind bender to relearn the fretboard in 4ths. 🤪 Transitioning back really makes me appreciate all of the great things about a 4ths tuning system. Truth be told, I hadn’t been practicing bass much in the past 5 or so years, I’ve mostly been focused in on cello. But! Changing my tuning back to 4ths is forcing me to practice 😁 So! Every time I practice, I create multiple exercises and then work on it until I have it in the hands. Sometimes it is hyper focused on a certain technique or theory, but other times it is free spirited. This one came out of pure improvisation, and it is a finger twister! The concept is to play Root 5th 4th in the hand (ex 1 3 1) then Root 5th 4th again but as a 1×2 extension where 2nd finger replaces 3 (or stays put if already extended) in order to shift up a position to play the 4th on the lower string with your 4th finger (1×2 / 4). Then you are a up in the next position and can start the climbing cycle all over again! The key to this exercise is to lift 1st finger off the board when you are on 2nd finger and about to shift up, leading with the 4th finger. Good Luck!
