Music, Machine and Human Relationships.

Following on from my last post about Error 0xHUMAN: System Overdrive, I wanted to introduce another music project that plays on the intersection between AI and musicianship. A new work by composer Zeno van den Broek premiered at the Gaudeamus Festival in Utrecht on 10 October with AI powered drum robots developed specifically for the show.

The robots are responsive, learning from the music as it is played by humans. They can develop their own ideas as well as respond to the music that they are emersed in.

This is a step away from playing with a pre-programmed machine, at which point the musicians are slaves to the rigidity of technology, as the technology can influence the sound produced itself.

Another aspect that I find interesting is that the musician has developed a way of communicating with the robots using gestures, very much as we ‘live’ musicians do between each other. And the robots have a light system that they themselves can use to communicate with those surrounding them. They might want to make a change in the structure or sound for example.

The robots can ask for the materials that they play to be changed (maybe from wood to metal), and they can make these requests whenever they ‘want’. The timing of requests changes too, with changes requested more or less frequently at different points by different players.

There are a lot of similarities here with the Error0X:Human project. The line between AI and machine production and human production is blurred. AI is an artistic tool that might also be seen as having its own agency. Both projects raise lots of questions about art, authorship and creativity.

There is an article in the Dutch newspaper Trouw available in which the band members (the human ones) talk about their experience. One of the aspects is that the robots have names and really aren’t spoken about as if they were machines, but as band members. They have gone beyong machinery and into something that has agency. It’s a lovely article to read.

And if you can get to Bucharest on 20th September my colleague Luca Severino is bringing the Error0X:HUMAN project to a new public in a new format…. See below, on full screen.

Marketing High Quality Digital Music, PONO

I have never managed to get into digital music for several reasons. I don’t like wearing headphones, I get paranoid as I hear people calling my name in the background, and I think that they distract people’s attention. This is really noticeable while I am riding my bike on the pavement with the kids. People who are walking while listening to headphones are less aware of their surroundings, they tend to zig zag while they are walking and they cannot hear you coming.

This report in Businessweek addressed the problem a few years ago, although it has many methodological issues, and this article on the Treehugger website offers similar data while raising some good questions about the intentions and interpretations.

In Kenya they seem to be taking the problem seriously and in fact it will soon be a traffic offense to cross roads in Mombasa while wearing headphones or on the phone if legislation proposed by the Mombasa County Assembly is approved.
So no headphones means I don’t have one of those miniature storage devices to listen to. But I have never really got into digital downloads either. The problem there is quality. I like vinyl, take a look at the photo below of my record player.

My Sharp Record Player

My Sharp Record Player

This is a beautiful machine, 1983, plays both sides of the record, sumptuous quality, style personified and even comes in a portable version (mine also runs on batteries but the speakers don’t attach as the portable versions do).

So I have never had a system to play digital music that is half as good as this, although recently I have got closer with the Studio Pro 4 speakers that I found by the side of the street here in Cambridge (see this post for details). But even taking that into account, the sound is just not the same.

I have a vinyl and CD copy of the Beach Boys 20 Golden Greats, and playing the two together the difference in enormous. The digital version is sharper and the sounds are purer, but that was not what the boys had in mind when they were recording it. On MP3 the differences are even more noticeable. But convenience rules nowadays, and streaming of low quality music reigns.

Now Niel Young is with me on this, as are Sting and various other musicians. Niel wants to offer high quality music reproduction to people like me, and is preparing to launch his new baby Pono.

The player looks a bit like a regular MP3 player, but the files are much bigger so not as easily stored or downloaded, but the quality is much higher (say those who are marketing it). You can find some statistics in the article above. The data would suggest a vast improvement in quality, but as ever the proof of the pudding as they say.

And there is a cost issue. The player will cost about $400, and an album maybe $25. This is obviously marketed at people who have some disposable income and are looking for quality, probably musicians in their 40’s just like me.

We might wonder how big the market is, but if we note that the project raised about $2.5 million on Kickstart in a few days, maybe there is enough money and enough people around to make it a success.

So the question is for the technology community, will you (or more importantly I)  buy it?

Coach Guitar App Review

Coach Guitar enables users to learn guitar without any music theory or tablature. The animated black fret-board represents a guitar and the fingers are marked with different colors to specify the positions efficiently for both hands use. The colored dots signify the different chords of an acoustic guitar to be strummed. These instructions are available in Help menu on the start screen.

When you open this app, the page shows options such as My Lessons, Library, Help and finally Settings. After going through the Help option, you need to start with My Lessons where there are few popular songs pre-loaded. Then, you have to choose one among them and proceed for the coaching sequences. Just like a true professional, this app provides a step by step teaching facility which helps the users to play each verse of the song with perfection.

Coach Guitar Navigation

This version also contains two amazing songs for free- Stairway to Heaven by Led Zeppelin and secondly, Wake me up when September ends by Green Day. Another interesting aspect of this app is the availability of video lessons in HD. You can watch and learn in no time. In the Library, you can buy and store your favorite tracks available which you want to learn. The Library is updated quite frequently for the convenience of users. Also, the developers have provided the settings option to configure this app as per your wish.

The appearance of Library is quite similar to that of a normal playlist in your phone only with a single modification of the price tag on the extreme right of the songs. This can be considered one of the flaws of this virtual guitar teaching concept. You have to pay a certain amount for adding up your favorite tracks further. The customers have complained about this attribute and rightfully so.

Looking at all the pros and cons of this guitar teaching app, I am pretty much satisfied by its functioning. This app skillfully acknowledges its name and acquires relevant features to teach users how to play a guitar. Coach Guitar version 1.7.3 requires only 13.2 MB of phone memory. With the presence of a large display screen in iPhone and iPads, the working of Coach Guitar becomes easier.
