Taken to the extreme, a solo act could memorize 1,000 songs, but at that point you're basically playing one song because the majority of the time you're doing everything with your tone, expression, phrasing and dynamics. I've seen that before -- it's one song all night long with not much differentiation.
Great point. That’s why I prefer duo gigs, both being singers. I don’t like hearing my voice for 3 hours, I’m sure people don’t either.
It’s also why I choose to read all my lyrics, rather than memorize everything. This greatly expands my capacity for songs, and I feel it’s a bit less taxing on my “mental RAM.”
Memorizing/recalling vs reading uses different parts of the brain, and I noticed that when I first started with performing mostly memorized material, then had to read a few songs for special requests or similar, I really screwed up the reading part a lot. I find it takes practice to be able to read and sing smoothly, so I do it all night so it’s consistent. Overtime, I eventually memorize the songs anyway, so I find myself not looking at the lyrics often enough - I don’t just stare at my lyrics all night regardless. Thanks to BandHelper and it’s auto scroll lyrics, the font is large enough to see and I can keep my place without having to manually scroll or change things.
I know people who are adamant about not reading lyrics, but as you mentioned, they tend to make everything sound the same as our mind basically has to “compress” the data somehow. They tend to change most songs to a standard 3 or 4 chord progression and just make it fit, so they don’t have to memorize the real chords, and also change the melody to whatever. Of course the words tend to be wrong in many places too.
Personally, my approach for playing cover sessions (restaurants, hotel hallways, occasional bar area) for some reason has always been to always play the correct chords and arrangements, unless I’m purposefully changing something. I got tired of seeing people do C Am F G for a songs like “Drift Away” or “Why Georgia” - you know, songs that obviously have distinct sections and movement, but they just play the same thing all song to make it easier. If me having lyrics and chords prevents that, I’m all in. I still mess up at times, but that’s bound to happen with 400+ songs rotating and adding.
No one has ever complained about me reading (except those musicians who homogenize everything), and many audience members do comment positively on the sound and song selection and quality on their way out or during my break. For my types of gigs, the audio quality and overall feel is paramount. My sound is broadcast to speakers throughout the hotel or restaurant and many people can’t even see me while I’m playing. They finish dinner and walk out realizing I’ve been playing the whole time and go “oh wow, great job I didn’t even know it was live music!” I take every comment with a grain of salt, but it’s usually positive and that’s all I’m trying to do.
