I always thought the KEYBOARD/Synthesizer was the weakest musical instrument in a band until I realized recently that a lot of songs I like, the Keyboard/Synthesizer is actually one of my favorite parts. A lot of time I was getting the guitar confused with the Keyboard/Synthesizer. For example, I love the "du du du du du!" Part of She Bop by Cyndi Lauper and I thought that was the guitar, but recently found out it's the keyboard/Synthesizer..

The drum is the foundation of the song, amd the guitar helps being melody and harmony.

I'd say the bass or the drums, for sure.
Sure they're not the most noticeable, but they have the strongest influence on the tone of the song/band at least in my opinion.

In my last band I either played the keyboard or electronic guitar, and depending on which instrument i played we sounded entirely different as a band, I give you that. Keyboard, especially when sounding like a piano made us sound like a boogie woogie group, and with the guitar it was hard rock. So yeah they make a huge difference, too..

But the drummer and bassist, those dudes have the real power

I think it very much depends on the style of music, the band, and the individuals involved. Bass guitar is a good example of this. In country music, it tends to relegated to a supporting role, while in funk it's one of the dominant instruments. In rock, the bass often takes a back seat, but it depends a lot on the bassist and the band. If the band is Primus, for example, then the bass is front and center.

It's not uncommon for people to underestimate or overlook the role of keyboards/synthesizers in a band, especially when they're not as visually prominent as guitars or as rhythmically foundational as drums. However, the keyboard/synthesizer can add unique textures, melodies, and atmospheric elements that contribute significantly to a song's overall sound.

In the example you provided from "She Bop" by Cyndi Lauper, the synthesizer plays a catchy and distinctive role in creating the "du du du du du!" part you enjoy. Synthesizers are versatile instruments that can mimic traditional instruments, create futuristic sounds, or provide lush background textures.

In many genres, keyboards and synthesizers play a crucial role in shaping the sonic landscape. In electronic music, pop, rock, and even some forms of metal, synthesizers are often responsible for creating signature sounds and memorable hooks. They can add layers, enhance melodies, and bring a level of creativity and experimentation to a composition.

It's great that you've discovered and appreciated the keyboard/synthesizer's contribution to the music you enjoy. Musical preferences are subjective, and each instrument in a band contributes to the overall sonic palette in its own unique way. Whether it's the driving force of the drums, the melodic elements of the guitar, or the atmospheric tones of the synthesizer, every instrument plays a vital role in creating a well-rounded and enjoyable musical experience.
