Half Hour Routine
Metronome: 10 minutes
2 minutes - set metronome to 120 bpm clap to every other beat
2 minutes - set metronome to 60 bpm clap to every beat
2 minutes - set metronome to 90 bpm clap to every beat
2 minutes - set metronome to 100 bpm clap to every beat
2 minutes - set metronome to 80 bpm clap to every beat
2 minutes - set metronome to 110 bpm clap to every beat
When you clap, try to "bury" the click so that you don't hear the metronome at all and just the clap.
Advanced 1: Start playing half the notes - every 4th beat at 120, every other beat at 60, etc. Tempo remains the same.
Advanced 2: Make the click the kick drum and play along (beats 1 and 3) - click is at half the tempos given above.
Advanced 3: Make the click the snare drum and play along (beats 2 and 4) - click is at half the tempos given above.
Advanced 4: Practice the "off" beats that are neither the kick nor snare (eighth notes). Kick AND snare AND kick AND snare AND kick AND snare etc. Practice just playing the AND after the one, the two, the three, the four.
Advanced 5: Practice the sixteenth notes between eighth notes. One EE and AH two EE and AH three EE and AH four EE and AH... Especially those leading into and out of the one.
Solfege: 10 minutes
Play a note on the bass & sing the note. D is a comfortable note for me, find a comfortable note for you and really lock it in until you can feel your voice vibrating with the note. Keep this going for 1 to 2 minutes.
Once you can do that, play a short melody on the bass & sing along to it. Play slow enough that you can hear your voice lock with each note. Nursery rhymes are good here - 3 blind mice, oh when the saint's go marching in is a favorite of mine, twinkle twinkle little star, etc. Practice for 5 minutes.
Repeat in a different key.
Advanced 1: Add in the click.
Advanced 2: Learn songs you want to know & sing & play the lines slowly.
Advanced 3: Keep the note the same & now sing the melody while the bass plays the root note only.
Advanced 4: No playing, just singing.
Technique: 10 minutes

Play the G minor scale at various tempos.

Play triads in the G minor scale at various tempos.

Play seventh chords in the G minor scale at various tempos.
Do this in different keys.
Practice both ascending & descending.
Practice inversions - dropping the 3rd or 5th by an octave.
Practice doing this over various chord progressions, perhaps some you find online for popular songs.
Attempt to connect chords by notes they have in common, or if they have no notes in common, then by "passing tones" - a note that's in between the notes of one chord & the notes of another chord.
Do this every day.
When you've got serious time to dedicate to studying, work out of a book - study your theory, learn proper technique, learn sight reading & learn basic bassline construction techniques from a book, but do this routine every day and you'll be a killer bass player in no time.
