(I hope you understand my poor English translated)
Is a very interesting topic. I interrupted the play guitar for over 15 years. I used to play classical pieces and a lot of Portuguese popular music. Together with friends we sang on weekends during the whole night around beer, wine, whisky and snacks.
At that time, I don't remember frustration.
Later, during a long period of my life I was moving around all weekend from place to place supporting my young kids’ sports activities. Had little time available for music. Currently children are adults around thirties. Also, I don't remember frustration, although I felt the lack of music.
About 3 years ago, I slowed my professional activity, and only drink wine. I have more time available now and my desire to play guitar returned. I discovered jazz and I was fascinated. The possibility of being able to create and each theme can always have something new, really fascinated me.
When I found out the wikiloops and the big amount of souls around the world who play and share their creations for fun, excited me. I went back to scales, modes, chords, arpégios, .... and I started using the 7th, and 9th 11th 13th, 6th etc ... fantastic!! The music shown other colors.
It was important sharing and listening to what others were doing and ... I learned a lot from my friends loopers, … and I am still learning. I never had the experience of playing with a band in the past (luckily my youngest kid did it for a period, now his professional activity does not allow).
There is a law of the universe that says the following: each new step in the evolution requires an increasing expenditure of resources.
I think this principle is well visible in the music. The more you evolve playing an instrument greater will be the effort spent and always with a smaller evolving speed.
Here arises a kind of frustration. How to fight it? Maybe with perseverance and support from their peers.
Here the wikiloopers are a great help, motivation from peers.
Another type of frustration derived from lack of creativity, where you always must create something new and different, and it doesn’t appear. It is a lot more complex.
Among a huge number of factors I believe that atherosclerosis has big responsibilities here too, by not allowing the brain blood abundant irrigation LOL.
However, change, do new things, new experiences, listen to different music, diverge, disagree, … it helps ...
