I have been playing for a couple of years now and I am having trouble figuring out how much time and effort I should be putting into memorizing songs.
When I started out I memorized a whole bunch of songs (50ish); however my goal is to become better at improvising and composing more than playing in a cover band. As I spend more time practising fretboard memorization and rhythm exercises I am finding it difficult to find the time to learn new songs and maintain the memorization of the ones I know. I find this especially tough because I am now focusing on figuring out how a bass line is constructed vs. Memorizing Tab.
So my main question is if there is a benefit to memorizing and maintaining a large number of songs if one isn’t playing them live?
Learn to recognize ... what you're hearing, and where those intervals are on the fingerboard. Then you don't need to memorize particular songs, as you'll be able to hear where they are going.
I don't see any benefit of memorizing songs unless you're playing them on stage and not wanting to (or being allowed to) use cheat sheets. Your time will be much better spent working on the things you've been working on. Once you learn "how a bassline is constructed," as you put it, you'll be able to remember and/or reconstruct lines that you haven't committed entirely to memory -- and also be able to improvise around them when desired.
@Sean150 Everything you need to know is in the answers already given.
But the reality is that there is no need to for a trade off. Given a structured approach, supported perhaps by learning a little theory, your goals need not be mutually exclusive...
Break out some paper and write stuff down as you go. Use TAB, standard notation (learn it if you don't already know it), fake chords, nashville numbers, or, to being with, whatever you are capable of. Add as much detail as you can - chord symbols, repeats, key and time signatures, bar counts, section lengths, tempo changes, etc. Go around as many times as necessary to get it right, but write everything down. Take an analytical approach. For example, when you add a chord symbol, look at the notes in the bass line and see how they relate to the notes in the chord. See how the rhythms and accents in the bass line fit with the time signature. Look at how a good bass line moves rhythmically and melodically to connect the chords. If you can, write out segments of the vocal melody and look at how the bass and top notes fit around the chord. You may not be able to do all of these things at once, but just giving it a go will at least open your eyes to the internal structures of the tune.
Once you have finished, put the bass down then write it out again as a final clean draft on a new sheet. Pick the bass up again and run through to check for mistakes, then put in an easy-access folder.
The process of doing this will:
- Show you how lines are constructed within the harmonic framework;
- Show you how the harmony (chords) relates to the melody;
- Show you the framework of the song - key(s), scales, motifs, themes - around which you can start to improvise in ways that make musical sense;
- Demonstrate principles of composition which you can apply to your own work;
- Give you a reliable reference library should you need to check or recall something in the future.
But here's the big one: in doing all of these things you will actually start to remember the songs more quickly, more completely, for longer and with a deeper,
more musical understanding of them. In turn you will make fewer mistakes at show-time meaning you play with higher confidence leading to a better show.
YMMV
