Building a product is like composing music. And building a great product is like creating a musical masterpiece. Great products are simple to use but they are deep, hence they grow on you and leave a lasting impact (just like a great musical piece). A thread 
I'm no musician but being a big fan of oscar winners @arrahman and @HansZimmer I have watched a ton of interviews and behind the scenes to understand how they compose such fantastic, deep (music that grows on you) but "easy to get hooked to" compositions.
We can use the same techniques to build amazing, long-lasting products. I know there is no oscar to win at the end but high customer satisfaction and a high NPS score should do 
Just like the V1 of a product, a musical piece starts with an idea and then the musician tries to compose the right melody (mostly in his/her head and a keyboard attached to a computer) and figures out the instrument which will become the centerpiece of the music.
But the musician also has a larger goal (just like the founder or PM) which is to create a gripping theme for the album or the movie and then figure out how each individual piece (or feature) will fit into the core theme (or the product).
After this the real task of implementation/composition starts. Finding the right instrument (technology), best players (developers/designers), jamming up with them (white-boarding), trials, and errors. Sometimes you realize the idea sucks and start over. And sometimes it works.
After this stage the similarities end. Because unlike a product that can be launched as an MVP, musicians can't launch and test their melodies before finishing the whole piece. Their job is tough--what they do from this point on is inspiring and we can learn from their techniques
In most of his interviews @arrahman talks about "improvisation" as his core technique to building musical pieces that grow upon you. That's why after listening to a song 1000+ times you will find a hidden sound/instrument that will keep you hooked like an addict for another year.
I'm still learning to build products and probably an amateur, but "improvisation" is the only technique I have tried to master. No one can build a sophisticated decision tree like this on day one

but you can always improvise!

So how do you improvise? 2 things -- feedback loop & insatiable appetite for customer delight.
The feedback loop is a PM's biggest advantage, right? A musician takes feedback from his team but mostly just the film director or the music editor. We can take feedback from our customers and use that to keep improvising for years.
An insatiable appetite for the great product--both @HansZimmer and @arrahman talk about not liking their own initial drafts and keep on asking their directors "is this shit?" This nagging sense of being unsatisfied delays their imp projects but the end result is mind-blowing.
This is my 2 cents on this topic. And that's how we do things at @TryEvaBot. I would love to know your thoughts and techniques you use while building your amazing products.
