Software I use (in no particular order) :
For pc and mac, not available on mobile devices :
“Band In A Box” : gives accompaniment at any chosen speed. A bit pricey, and you have to put in the chords yourself. A lot of styles (bluegrass, jazz,…) to choose from. And lots of bells and whistles.
“Audacity” : free software to edit audio files, for example adding effects. I use it solely to slown down songs of records so I can hear the solo note for note.
“MuseScore” : free software to create standard music notation scores. I only use it for arranging vocal harmonies.
“TablEdit” : cheap but good software to create and play tablature. Since I don’t use tablature a lot, I don’t use it often. Still, for its low price it still is worth it.
a metronome application, any one will do. Thàt I use a LOT !
For mobile devices, not available on pc or mac :
“iReal Pro” : like Band In A Box, gives accompaniement at any chosen speed. Dirt cheap, and it comes with a library of songs, eg 300 bluegrass standards that you can download. Also a lot of styles, but not as elaborated as BIAB. Worth every penny. [Correction : iReal Pro is also available on Mac, so no need for BIAB there if you’re happy with basic backing tracks. Yet the app is not available on Windows machines]
“Amazing Slow Downer” : does what the name says. Also very cheap, also worth every cent.
[Update : To amplify the sound of my mobile devices, I use JBL Charge 3, a Bluetooth speakerbox]
I have lots of instructional books, CD’s and DVD’s, like Jack Hatfield, Earl Scruggs’ book, the Murphy Method, Tony Trischka’s, etc etc etc etc. None of whicb I have ever fully completed. I have a reasonably developed brain, but when it comes to learning music, I have the attention span of a mayfly with ADHD.
That’s why I just tell myself to learn tunes. Lots and lots of tunes.
