7 Free Tools Every Musician Should Use

Ever since Napster, the world has become conditioned to want free music. Even though Napster is nowhere near the household name it used to be, there are new platforms that have taken its place, such as Youtube, Spotify, and Pandora. These websites do pay artists some royalties, but admittedly not very much.

It can be hard for artists to get fans to buy their music. (Don’t worry, it is possible to make a career as a musician though! Check out this new book by Ari Herstand  about making a living in the New Music Business. This is HIGHLY recommended reading!)

So…let’s turn the tables! Musicians, let’s get equipped with some free resources. There are many great tools out there, ready for you to use. Here are seven of them that you might not know about:

1.  Free DAWs

ProTools First

DAW stands for Digital Audio Workstation, and is the software that allows musicians to easily record, edit, play virtual instruments through MIDI, and compose.  One of the industry standards, Pro Tools, has a free version called Pro Tools First.  It has a some minor limitations that still incentivize purchasing the full version, but someone who doesn’t need to track more than 16 inputs at once will find this a wonderful tool.  MuLab is another free DAW that handles all the full features of a DAW you’d like while also offering hundreds of quality presets already built in.  Audacity is a great alternative for audio recording and editing. It doesn’t have the MIDI capabilities of these other DAW’s, but it has robust audio editing features. All three DAWs work on both a Mac and a PC.

2.  Free Samples

Cymatics image

There are some great resources out there for free sounds. Cymatics has incredible vaults of free samples and foley (sound effects) that they just give away! These are extraordinarily high quality sounds that normally would cost hundreds. I’m shocked that they give it away like this, to be honest.  They also have DAW presets for Logic and Ableton, that are top notch. Another incredible resource is, which has user-uploaded samples, with a searchable database.  You can find almost anything you’d imagine here! Looking for that particular sound effect for your sound design project?  These are the first places I’d start.

3.  Neil Patel’s Blog

This dude is absolutely brilliant. Widely regarded as the #1 marketer in the world, Neil Patel is constantly giving away invaluable advice and insights about how to maximize web visibility through social media and blogging. His marketing strategies can apply to virtually any field, including promoting your music. I personally guarantee that you will become a better, more informed, and creative promoter of any project, product, or artist by going through his free resources.

4.  MuseScore

Would you like to professionally notate and engrave your music, but don’t have the cash on hand for Finale or Sibelius?  Check out MuseScore.  MuseScore is an open source platform, similar to Audacity, available for both Mac and PC, and will allow you to easily create fantastic looking scores.

5.  Corridor

Corridor Free Music Education

Of course, we’re going to give ourselves a little shoutout here.  We’ve built the best way to learn chords, chord progressions, melodies, rhythms, notation, ear training, and keyboard skills, and it’s free.  We believe that to truly learn music, you must be able to see, hear, and play every concept.  Through Corridor, you will learn to play by ear, learn about chords through chord symbols and notation, and apply every musical concept to an instrument. We have tutorial videos, interactive games, and work on any device. We might be crazy for doing it, but we want you to be the best musician and artist you can be…for free!

6.  MailChimp


Few things are more impactful and important for a musician’s career than being able to easily connect with your fans.  Through MailChimp, you can customize emails from the ground up (no coding skills required), easily build a subscriber list, and quickly send out emails to your fans. MailChimp is completely free up to 2,000 subscribers.

7.  Sound Exchange

Sound Exchange

A lot of people know about ASCAP and BMI, but Sound Exchange is a company that specifically collects royalties from online streaming sources, such as Spotify and Pandora.  It’s easy to register your songs, and it sure is fun to have a check show up in your mailbox from time to time.

Top 5 Funniest Videos if you Know a Little Music Theory.

We went around Youtube and put together the top five funniest videos that utilize music theory that we could find. Some of these videos are funny no matter who you are, and some of them get the most laughs if you’re a music nerd like me. Did we miss some that should have made the top five? Add them in the comments below!

1. Music Theory class

Why it’s funny:
We’ll admit, sometimes music theory can be taught in a bland fashion. (Hey music teachers: don’t make music boring!  Use this to help you out.) Here’s a cute critter falling asleep and looking generally befuddled while someone talks nonsensical music theory.
Theory knowledge required for maximum hilarity: Low.



2. How to read music

Why it’s funny:
Because it’s true! In a dry yet hilarious explanation, this video shows some of music’s stranger idiosyncrasies, such as infrequently used clefs, inconsistent tuning pitches, transposing instruments, and breathing articulations. (Credit to Julian Cianciolo for the great video!)
Theory knowledge required for maximum hilarity: Medium.

3.. Metallica – National Anthem at the 2015 NBA Finals
(Jazz Ballad Version)

Why it’s funny:
This is pretty hilarious to anyone, as long as you know that Metallica is a heavy metal band, and not a jazz duo. Seeing James Hetfield and Kirk Hammett play a surprisingly tasteful and sophisticated re-harmonization of the American Nation Anthem is definitively worth watching. (Just to be clear, the audio has been overdubbed, but with an extraordinarily high attention to detail. Kudos to the people over at Endless Noise for their great work on this!)
Theory knowledge required for maximum hilarity: Medium.



4. Music Theory Song (Chestnuts)

Why it’s funny:
Who doesn’t like humor put to Christmas music??? Some of the terms here get a little more advanced, such as “mediant” (which is the third note of major scale) or “V of V” (cliff notes: this is a major or dominant chord built on the second degree of a scale).
Theory knowledge required for maximum hilarity: High.


5. Axis of Awesome – Four Chord Song

Why it’s funny:
There are a lot of really well-known songs that use the same four chords in the same sequence. Everything from Journey to Disney to Beyonce to Offspring in here. Lots of pretty ridiculous costumes in here are the icing on the cake. (Credit to Axis of Awesome)
Theory knowledge required for maximum hilarity: Low.

6 Ways To Be A More Creative Musician In 2017

As a musician, few things are more important than developing our own creativity.  Our ability to write meaningful songs, to construct inspiring instrumentals, or to find innovative ways of adding post-production nuances depends on our ability to think outside the box and find new, unique sounds.  Here are 6 ways you can up your musical creativity this year.

1.  Write on an instrument that you don’t usually play.

We often get into musical ruts, as we depend on the muscle memory that we’ve formed on our instruments.  Many of our songs, many of our solos, and many of our mixes end up sounding the same (for better or for worse), because we keep going back to what we know.  Try mixing it up!  If you’re a guitarist, try writing your next song on piano.  If you’re a songwriter, try writing an instrumental that still conveys a story. If you’re a producer, try a new sound library that you haven’t used before. Putting yourself into a new situation will force you to be a creative problem solver.

2.  Get better at what you do play.

One of the most memorable master-classes I’ve ever attended was by jazz pianist Benny Green.  Benny is one of the hardest-swinging, most burning pianists out there.  He was asked during this master class what the next step is in his musical journey, and his answer amazed me.  He wanted to be a greater technician on his instrument.  He said that he has all sorts of ideas in his head that he can’t get out, because his hands and muscle memory can’t keep up.  Woah!  So, don’t let your lack of technical ability on your instrument or knowledge of your DAW hold you back! 

3.  Listen to music that is new to you.

This is a simple one – get out of your comfort zone!  Listen to a genre of music that doesn’t naturally appeal to you, but listen to it with open ears.  Listen for nuances, the grooves, the musical phrasing, the chord progression, the instrumentation…whatever catches your ear.  Take the best ideas of the genre and brainstorm how you can apply it to your own music.

4.  Have a jam session – but listen to another band mate more than you listen to yourself.

Hold a no-agenda jam session with some of your friends…but don’t focus on yourself!  Let your ear wander around the room and try to lock in with new things:

What sort of range is the keyboard playing in his or her right hand?
How might you change what you’re playing based off of the rhythm pattern of the bass guitar?
How might you change what you’re playing based off of the rhythm pattern of the bass guitar?
* What is the drummer’s non-dominant foot doing?
* When is the vocalist breathing?
* What is the picking pattern of the guitarist?

5.  Pseudo-transcribe your favorite artist.

One of my favorite things to do is pseudo-transcribe.  Let me explain.  Imagine you just went to a concert to hear your favorite guitarist of all time.  The venue, however, was very strict about not allowing recording devices.  Mid-concert, your favorite guitarist plays the most incredible, creative, inspiring riff you’ve ever heard…but you have no way of recording that exact moment.  So, you try to burn it to your memory.  You listen intently, focus on every note, and you hum the riff to internalize it.

Then, when you get home two hours later, you pull out your guitar and start trying to figure out what you heard.  But, unless you have a photographic memory, chances are good you won’t be able to recall that riff exactly, note-per-note.  Instead, you end of up transcribing the impression that this riff had on you.  You recall the general idea without the specifics, and in turn you end up personalizing the riff.  It’s now a part of your own musical vocabulary!

6.  Learn music theory and develop your ear.

The more you know about musical concepts, and the more quickly and accurately you can connect your ear to your brain, the more creative you can be.  Think about being a poet—the more words you know, the more innovative and intricate your rhymes and stanzas become.  Unfortunately, there’s only so much you can do with a limited vocabulary. 

When it comes to music, the more tools you have in your toolbox, the better.   You can learn about which chords tend to go together, so you know when to break that tendency for maximum impact.  You can apply less-often used scales to form inventive melodies.  You can dive into chord structures that broaden the harmonic landscape of your music.  There are endless possibilities!

I would love for you to make Corridor a part of your musical journey this year.  I believe that using our program will help you become a more creative and skilled musician.  Better yet, Corridor is FREE to all users, making this invest in yourself a no-brainer.  I honestly believe you will love it.
