We take an in-depth look of the magic of Dirnt's bass playing
Saviors, with its smartly conceived, stadium-sized fifteen tracks, is both an impressive artistic step forward and a sonic and stylistic return to vintage Green Day. After all, Mike Dirnt still anchors and propels the band with his power-pick parts, in sympathetic spasms with drummer Trรฉ Cool and guitarist/vocalist Billy Joe Armstrong. Best of all, with the passage of time, Dirnt has continued to develop his musicality, to the torrid trioโs benefit. This can range from subtle moves like playing fifths or octaves under a stream of steady root notes to add impact in a chorus, or adding what he calls a โ2k popโ by playing harder in spots to produce a frequency that cuts through the mix, to adding counter-melodies, polyrhythms, and low-to-high movement to create musical and emotional sub-hooks in a song. โIโm always looking for windows. Places in the music where I have the opportunity to contribute to and serve the song.โ

Ex.1 shows the opening unison riff of โOne Eyed Bastard.โ Note how Dirnt prefers to stay on theย Aย string, jumping from the 7th fretย Eย to the openย Aย in measure 2. Conversely, he remains in 7th-fret territory for his one-bar fill at 2:19. Try to lean back on both. He offers, โWe love shuffles in Green Day; thatโs our wheelhouse. The swing feel gives you a lot of options on bass. You can sit in the pocket or you can find a counter-melodyโalmost like youโre playing a horn part.โ

Ex. 2a contains the B section groove from โ1981,โ at 0:42. While the first two measures double the guitar riff, bars 4-6 ride the root of the chords until Mike steps out melodically in bars 7-8. Here he ascends and descends via anย F#ย dominant scale (weโre in the key ofย B), moving chromatically from the 7th to the root at the apex, across the bar line. He explains, โI just wanted to add movement and create a dramatic resolution to the phrase. But the key is itโs teed up by me flipping the rhythm in the first two bars. Then I go back to playing the roots [in measures 3-6], and the last two bars are the answer to the opening rhythm. Thatโs all inspired by the bass player in The Rezillos [Dave โDr. D.K.โ Smythe], who would do intersting rhythmic things.โ Play the lines slowly at first, to get them under your fingers, before building up to the super-fast tempo.

In Ex. 2b, the bridge, at 1:13, Dirnt issues an ear-grabbing counter-melody that starts on the same note as Armstrongโs vocal but descends differently in bars 2 and 4. Then in 5-8 he basically mirrors the vocal melody. He notes, โI was playing along to Billyโs vocal and resolving my part the way I heard it, which happens to be in harmony with what heโs singing. He liked it.โ The trick is to be locked into the steady 8th-notes but also retain a singing mindset when the notes move.

Ex. 3a is from the opening section of โComa City,โ when the full band enters, at :21. Dirnt rides the roots until theย Vย chord in measure 4, where his stated love of walking bass lines emerges via the climbing line. In bars 11 and 13 he again shifts from pumping 8th-notes to mirror the rhythm of the lead vocal with his own potent counter-melody. โThatโs me dancing along with Billyโs vocal melody in my own way,โ he smiles.

For Ex. 3b, at 2:43, which is a rideout on the tonic, Mike switches from steadyย Bย 8th-notes to a descendingย Bย major line for contrast and maximum melodic impact. โJust breaking up the monotony of the same note by adding some motion.โ Be sure to keep the driving feel in both examples.

Ex. 4 shows the band unison riff from โLiving in the โ20s,โ at :07. In an interesting quirk, Dirnt plays the firstย Bbย on the first fret of theย Astring before jumping to the 6th position to complete the phrase. He reveals, โI wanted that bite on the first note; itโs too round if I play it up on theย Eย string.โ Sit square in the pocket while leaning forward.


Finally, Examples 5a and 5b are from the acoustic power ballad, โFather to a Son.โ In 5a, at 1:01, Dirnt brings some melody to the four-bar transition before the second verse, while also establishing the bass line rhythmic figure of quarter-note, dotted 8th-note, and 16th-note pickup into two more 8th-notes. โHe allows, โI wanted to play something emotionally suited to the song. I got the syncopated rhythm from Treโs kick part.โ In 5b, at 2:42, which is the second time through the songโs B section, he maintains the bass line figure before once again stepping out melodically with another slide-induced fill. Put on your ballad hat for these, but retain your edge.
