There is a specific kind of adult who hears the first four notes of the Pokémon theme and immediately feels ready to bike into tall grass and pick a fight with a wild rodent. If that adult is you, congratulations: your reflexes are intact and your priorities are exactly where they were in 1998.
This clip is the "Gotta Catch 'Em All" main theme arranged as a fingerstyle chord melody for solo guitar — one player, one instrument, melody and chords stacked together so it sounds like the whole intro, not just the tune whistled in the shower. Tabs are available if you want to catch it yourself.
How a fingerstyle chord melody works
A chord melody is the trick that lets one guitar do the job of a whole ensemble: the melody note sits on top, as the highest-sounding voice, while the chord underneath fills in the harmony and a bass note anchors the bottom. The ear naturally tracks the highest and lowest notes, so as long as the tune is clearly on top and a root is holding the floor, the middle can be sparse and your brain still hears "full arrangement." That is the whole illusion.
The concrete takeaway: don't try to voice every chord in full. Keep the melody note ringing on a high string, grab just one or two supporting notes plus a bass note underneath, and let your thumb and fingers pluck them together instead of strumming. If a shape is a stretch, drop the least important inner note first — the melody and the bass are load-bearing, the rest is decoration. It also helps to work out the melody and chords separately before gluing them together.
Fun fact: it took me longer to fret this cleanly than it took ten-year-old me to actually catch 150 Pokémon. If you'd like the tabs and the Guitar Pro file so you can suffer productively too, they live on my Patreon.
