Percussive Fingerstyle: Intro to Slaps and String Hits

An acoustic guitar's soundboard and strings are a drum in themselves. Adding hits to your playing gives you a drumbeat-like rhythmic skeleton — this is where the “one-person band” of modern fingerstyle comes from.

The prerequisite is the muting / chucking you learned in Stage 5 — slapping is really an extension of those.

Modern fingerstyle hits different parts of the guitar for different “drums”: kick drum (boom) = a straightened middle finger or the base of the thumb, striking the lower half of the soundboard in front of the bridge; snare (chk, crisp) = the joint at the base of the middle finger striking the top corner of the soundboard / pickguard area; snare (string-on-fret) = a few fingertips slamming straight down onto the 3rd–5th strings; hi-hat (tss) = a quick scrape along the wound bass strings. First get the two tones “kick + snare” clearly apart.

The easiest one to start with is the “thumb slap”: with the thumb in a thumbs-up hitchhiking shape, slam the thumb joint onto the lowest two strings right up against the bridge, then relax and bounce right off so the chord keeps ringing (don't choke it dead). The closer to the body the warmer the sound; the closer to the fretting side, the clearer the attack.

Kotaro Oshio's signature is the “nail attack”: using the backs of the middle and ring fingernails to quickly brush / strike the strings for a percussive sound, while the other fingers keep plucking the melody as usual — the sound comes from the backs of the nails hitting the strings (not strings hitting frets), and the moment you contact the strings you snap right back toward the palm. This move usually takes a month of practice to smooth out, so don't rush.

More advanced still, there are full combination techniques PM and AM (splitting the kick and the strum between the base of the thumb, the middle and ring fingers, and so on). You don't need all of it as a beginner — first get a steady “pluck once, hit once” alternation going.

Further along there's also tapping (the right hand hammering directly on the fretboard to sound notes) and the combined technique of stacking “slaps + harmonics + tapping” together — that's the distant scenery down this road. Keep the rhythm steady and each individual piece clean, and you'll naturally come within reach.
