Play by Ear Using Audible With Complex Multiple-Instrument Music

     Not sure if that's the clearest title ever.  In case it's not clear enough, this article explains the process by which I learn a song by ear, when the song has a full band playing several (or many) instruments.  Especially if they're being jazzy and the melody switches between instruments, while they're all playing at the same time.  Even more so if I'm trying to play it in the original fashion, instead of in my own style.  I'm assuming that you already play by ear, and can pick out a melody by listening to the original music.  My rule of thumb used to be, if I can whistle it, I can play it.  These days, there's a caveat... I also have to be able to remember the whole tune without forgetting what it sounded like.  This is the process I follow when simply hearing a song isn't enough to be able to play it back.  It's mainly useful if you're struggling with memory issues and can't remember the entire song in one piece right off the bat.  Occasionally, it's exceptionally helpful to break down a too-complicated part of the music so I can hear exactly what notes they're hitting.

    Case in point, I'm trying to learn the University of Georgia Bulldogs "Glory Glory Dixieland" at the moment.  I've played my own version of Battle Hymn of the Republic for years, in a Southern Gospel style.  There's some commonality with Dixieland, but a lot of differences too. 

    Most of the time, I learn by listening, matching the keys, doing a ton of repetition to help remember the melody.  Easy enough, the only hard part is matching the key if it's not one I'm good at, and remembering the full melody if it's not a tune I already know well.  But this version of the Battle Hymn is in a key I'm not great with... and the melody drifts in and out with the different instruments like a fox laying a trail for the hounds. I'm not familiar with the patterns the band is using.

    There might be better options, but I'm a big fan of "Free", and Audible is free, open source, and a fantastic audio editor.  As usual, I only learn what I need as it's needed. Audible is way beyond me in all the many things that it can do, it helps to focus just on the useful parts.  I use it to adjust audio clips, digitize audio from very old VHS tapes, and to make sure all my audio is output in WAV.  WAV is uncompressed and lossless, and excellent for aligning a sound track with a video.  Learning to play a song with Audible is a new process for me, but as I get older and my memory declines, it's become a great help for learning songs in smaller chunks of sound.  And in the case of "Glory Glory Dixieland", slowing the audio down enough to hear the distinct notes being played is a Godsend.

    When a song doesn't have a clear melody being played by a single instrument, listening to a small segment over and over will also help you pick out which line you prefer to follow.  In "Glory Glory Dixieland", at times there's a jumble of sound.  I'll listen to it until one part stands out over another part, and pick that as the melody to follow.

    To start, open Audible and load the music file.  If you simply play the file, it will play the complete song and stop.  If you click and drag sections in the audio track, you'll highlight a portion of the audio.  Now when you play, it will play the highlighted section and stop.   At the end of the playback controls, clicking on the "Loop" command will add  a looping region that matches your highlighted section. (It shows as two bars in the timeline above the audio track.) Now it can play that one loop over and over, and you can focus on that one brief clip until you've figured out the notes you need.  

   Right click on the loop track, select clear, and you can choose another section to highlight.  Or select either side of the selected range and drag to reposition them. Listening to the music, piece by piece, you can learn the entire song in this fashion.  

    If the music is fast, or too complex at normal speed, you can slow it down.  For a quick fix, there's an information line below the tracks, and in that line you'll see a green arrow.  Hovering over it shows "Play-At-Speed."  To its right, you can change the speed it plays back by sliding the button.  This will change playback speed on the fly.  It's great if you just need a quick comparison, but as you change the speed, the pitch will also change, meaning it won't play back in the same key.

 

  Highlight the entire audio track, and from the "Effect" dropdown menu, choose "Change Tempo."  This will let you adjust the speed to your liking.  (I like to reduce the speed by about 30% for breaking down fast segments.)  If you click "Preview," you can hear a short sample with the new setting.  If the new speed sounds right, click "Apply." Now you have the entire song slower, but still playing in the original key!

    Save your work when it's done processing.  I export a WAV file, then save a "Project" file.  If you want to change the speed again at a later point, reload your original audio and make the change.  Reason being, changing the tempo while keeping the pitch results in artifacts in the file.  I haven't noticed them at one iteration, but the Audible website says it gets worse with each iteration, like making a xerox copy, then a copy of the copy, then a copy of the copy... it winds up losing quality.

    Now it's just a matter of learning the song at an easier pace.  Choose a small segment, listen over and over until you can match it.  If there's too many instruments, keep replaying the section, but listen for a melody that stands out over the rest of the instruments.  When you're trying to convert a whole band into a single person playing on the piano, you have to choose which parts work best and which parts aren't necessary.  I'll learn several segments, then practice playing them all in one run, then adjust the highlighted playback to the longer segment, and learn to play all those parts in time with the audio clip.  I'll learn the song as I go, and wind up being able to play along with the original music at it's original pace.  (Unless it's original speed is too fast for me to keep up!)

As always, I'm primarily writing this to accommodate my own memory loss.  If the time comes I can't remember how, this guide will remind me.  If it helps anybody else, that makes it even better.  :^)

Goodbye World Goodbye: Getting VHS Video Transferred to the Computer

    Last night's post was all about the end result.  Getting to play a duet with my uncle, and sharing it with the world.  Today's going to be the "prequel."  The story of how it got from a 2-decade-old videotape, to the state it's in now, and how I hope to get the real video uploaded eventually.

    To begin with... that photo was taken in 1962.  Freil was the youngest of my aunts and uncles, the baby of the family.  I was two at the time.  Mom's always said Nanny (her Mom) didn't get to see me until I was two, because of Dad's Navy career.  Nanny said I was walking already the first time she saw me.  So, just guessing, this photo might have been during that first visit.

    Fast forward to 1996, there was a family reunion.  We have a huge family, reunions were a big thing.  Freil was there, and of course everybody begged him to play.  I got a pretty long video of him playing.  At one point, he tried to 'escape', and asked me to play.  I've never been as good, but what I know, I learned by watching and listening to him.  Instead of letting us switch, someone asked us to play a song together, and Goodbye World Goodbye was the result.  It was one of those perfect moments, where everything goes absolutely right.  

    The rest of the video was mainly reunion events.  Later, I edited the raw footage, using his music as background track for the scenes.  By the early 2000's I'd sold or worn out most of my equipment, including the Hi-8 Camera.  The original tape is (I hope) somewhere in a box in our shed.  About 2016, Mom brought out one of the edited vhs reunion tapes.  It would have been a third-generation copy- raw Hi-8 to SVHS Master Edit, to regular VHS done using a 6-deck setup for small production duplication.  Better than home quality, way below broadcast quality.  And regardless, it's not optimal to have a final product at 3 generations. Back in the days of analog video, each generation lost significant quality.  

EZCap Video Grabber... not as good as it used to be 

  I bought a cheap transfer device from Amazon - EZCap Video Grabber.  It wasn't great, but it got the job done.  I borrowed Mom's VHS tape, and used an old VCR we still had.  It didn't come with software, but provided a link to free software.  It was already old when I ordered it, but with some tinkering and some online guides, I got it to work on Windows 10, on a computer I no longer have.     
    Now, that one video is on a file on my computer.  It's a poor scan, made from a 3rd-generation copied vhs tape. The video quality is not good enough to rescue, and the footage of Freil was mostly edited out anyway.  All I could save was audio of some of his playing, and that was muddied by background crowd noises.  That was the intent way back then... to use his piano playing as background audio for the reunion.  The conversations, the meal, the prayers, the announcements... I never thought it would be used to rescue Freil's music from.

    I'd forgotten the file existed.  Even that computer is gone, but I always save the internal hard drives from my old computers and add them to the new one.  Recently I was trying to make the EZCap work again.  Some programs acknowledged it's existence (VLC), but none of the ones I tried were compatible with it, including the original software.  It was while trying to run the old software, I found that old family reunion video.  Pure luck and coincidence, but I'll take it.  Sometimes you have to work with what you've got.

Serendipity plus hard work

    Even though the quality was bad, the audio was recognizable.  Hoping for an easy solution, I tried loading the file on Audacity, but Audacity can't load video files.  I tried using HitFilm Express (a free video editor) to separate the audio, but couldn't find an option to save the audio without the video.  There's a lot of results when you google the question, but I wound up using VLC, a free video player with a lot of options.  THIS SITE has a slightly outdated guide, but it was close enough to get me there.
    By the way, Audacity is free too... and a fantastic audio editor.

    With a 33-minute mp3 audio file, I used Audacity to convert it to a WAV file.  WAV is uncompressed, and will always play the audio at a consistent bitrate.  Mp3 is compressed, making it hard to match video clips with perfect timing.  When the whole video is just a single photo it doesn't really matter, but old habits die hard.
    From the Wav file, I edited it down to "Goodbye World Goodbye", equalized the audio trying to highlight the piano and de-emphasize the crowd noises, and exported it as a 32-bit Wav.

    Then back to HitFilm.  Create a project, import the Wav file, drag it into the timeline.  Import the photo, drag into the timeline, stretch the photo duration until it's equal to the audio track.  (It will snap in place when it gets close enough to the audio duration.)  Export the video to hard drive, upload to Youtube, and done.

    I'm still searching for the original raw footage of Freil playing on Hi-8 tape.  Once it's found, I'll have to obtain a Hi-8 player.  My plan is to buy an old one for $200-$250 from eBay, use it for any Hi-8 tapes I have (Not just Freil's, but any I may still find in all those old boxes.)  Then re-sell it on eBay.  It may not break even but at least I won't be out a couple of hundred dollars!

EZCap is outdated, but there's a better way to transfer video to computer

    Though I was able to transfer video using EZCap in the past, I can't recommend it.  It was a pain to get working all those years ago, and now it's not working for me at all.
    The best way I've found to transfer that footage into computer (meaning "effective, yet cheap") costs about $50 from things easily found on Amazon, plus some free software, all of it compatible with an ordinary computer running current Windows.  You'll notice I'm fond of free.  In this case, the list of items, along with a video explaining how to do it, was created by a YouTuber named "JUMBLE."

    There's not much sense in me duplicating his work.  And I don't want to divert his Amazon links for the items you'll need, that's very likely a source of income for him.  So, go watch his short, interesting, and truly informative video, "VCR to Computer - How to connect, watch and record old VHS tapes."  It's well worth the few minutes.  He doesn't add "fluff" to his videos.  It's all solid info.  He provides links to all the hardware, making it very easy to follow his instructions.
