Off the top of my head at this time of the day (night ) I can think of Black Sabbath’s NIB that has some in the intro and in other places too. I’d class this song as easy although I gotta admit I haven’t tried learning the solo yet.
If you are also interested in solos, Paranoid and Ironman are full of those.
Not that I know too many solos but all of those I do, have them…
Well, after some more digging around, here are two songs I came up with:
Thunderstruck by AC/DC
Nobody’s Fault But Mine by Led Zeppelin
Thunderstruck is way faster tempo than ideal, and Nobody’s Fault only has pull-offs, plus I’ll have to replace the bends with slides since I’m not string-bending yet. But, they are both songs that I’ve loved for decades, so the motivation to practice them will be high, which is most important to me.
I’m still hoping to find a 12-bar Blues progression with a riff that includes HO-PO (with no bends), or a Folk/Americana song with HO-PO embellishments added to the chord progression.
The concept of legato is to do with speed. Rather than pluck everything you pluck once and hammer on or pull off to get the other notes quickly. With practice you can play without plucking. So you can use legato to play any solo fast or slow. Ritchie Blackmore used a lot of legato.
IIRC the intro to Thunderstruck, which uses an open string as a pedal, was played in the studio with a guitar with only one string on it.
PS: if you really need a riff with hammer ons and pull offs try “Oh Well” by Fleetwood Mac (the original band with Peter Green).
Hey @Fast-Eddie, to me hammer-ons and pull-offs, no bends, means folk music. Try some of Neil Young’s easier songs. Heart of Gold has a hammer-on (just 1, I think) in the little riff. Needle and the Damage Done has a few hammer-ons (though not really a beginner song). I think Hey, Hey, My, My also features some hammer-ons and/or pull-offs.
By the way, you can take any most any riff you know and change a note here and there into a hammer-on or pull-off. Find a riff that has 2 consecutive notes on the same string where one of them is the open string (easiest case). If the open string is the first note, pluck it and hammer-on to get the 2nd note. If the open string is the 2nd note, pluck the fretted note and then pull off to the open string.
